Well, I wouldn't call it propaganda like a previous poster, but I do agree that the analysis is a bit off. My take:
#1 Mexico - The Royal Mayan is the 2nd oldest of the Royals and will soon be going away when the trust expires in 2013. Then there will be NO Royals in RCI. Also, trust me, the Sands and the Hacienda's are the nicest of the 4 (the staff is GREAT at all of them which is why they're in the top 4 but the are not ALL the "same").
#2 Hawaii - You don't mention the Top 30 in Hawaii at all!?!? RCI does offer the Hiltons which I am confident are very nice, but I don't think RCI offers the quality of the Marriott and Westin on Maui. Same goes for Kauai...so overall I'd give II the edge in Maui. (but Maybe it's closer to a wash with Hilton). Also, the ONLY place II doesn't offer a top resort is on the Big Island....
#3 Skiing - You mention the Beaver Creek but I think II would have the advantage in UT and Tahoe (none in Top 30 so maybe doesn't matter), and certainly Avon/Vail.
#4 Caribbean - You also fail to talk about the Caribbean/Bahamas Top 30 at ALL. The Marriott and Starwood presence (Harborside Atlantis) here clearly trumps RCI as RCI has no Top 30 resorts in this area.
#5 Limits - Contrary to your post, it is not impossible to get into most, if not all of these resorts. Even ski weeks at the Marriotts are often available. There have been PLENTY of 4 Seasons units this past year and Hawaii Marriott/Starwood has been almost "easy" to get into. You are just wrong making the assertion that it take a top 30 resort to get into a top 30 resort most of the time. It doesn't...maybe that's your experience with RCI. I personally will be staying at Harborside Atlatis, 2 consecutive weeks Westin Kaanapali, Hyatt Carmel, Mariott Grande Vista in Oralndo, and the Royal Sands and Hacienda's in Mexico...NONE of those trades made with a top 30 resort. Again, maybe top options are not that easy to get with RCI.
#6 Number of locations - I'll give you that. RCI does offer double the resorts and many more locations than II. I just don't know how confident I am about the quality of those options.
Bigger Picture - like I previously posted, I think there are MANY quality resorts in RCI I just don't think it's as easy to know what they are. RCI's rating system is no more objective than II's (I just disagree with you about this one). I DO however believe the Top 30 list could just be skewed to II and the brand names. For the most part it's because there is a level of consistency that helps those reviews....I think there are probably some top notch RCI resorts that just don't get the necessary exposure because they aren't part of a "brand."
I agree that II has an edge on the top 30, but that edge is mainly Marriott. There are only 2 four seasons, so all the II members can't stay there every year. There are 5 Mexican Royals, and I doubt that many II owners stay at one of those 5 every year unless they own there. Plus I never exchange for the same location every year anyway. If I love an area enough to go every year I buy there.
#1 Mexico:RCI has 356 resorts including The Palaces (Adventura, Moon, Cancun, Cozumel Palace, etc), Club Intrawest, and so many luxurious resorts (including many all inclusives II doesn't have) that you will never stay at them all. Do you really think the 5 Royals are the only places worth staying in Mexico? I am not saying nthey aren't the best, but the Palace resorts have to be a close second.
#2 Hawaii: RCI has 109 resorts, II has 58. From my quick count, with RCI you can stay in 38 of the 58 II Hawaii resorts. Obviously with II there are a maximum of 58 resorts to choose from, leaving 51 more options as an RCI owner. Not having Marriott access is a big loss, but having 51 more resorts to choose from should be worth something.
#3 Skiing: RCI has 199 Rocky Mountain Resort choices versus the 82 available from II. Yes Marriott is missing again, but there are other very nice places to stay than Marriott's and aren't most days spent skiing anyway? My point is that I would rather have a chance of getting a ski week at 199 different resorts than a chance of getting a week at one of only 82 resorts.
#4 Carribbean:St Martin RCI can trade for every resort II has (11). RCI has an additional 14 resorts (25 total) to trade for on top of II's 11. RCI has 12 resorts on Nassau versus 3 at II. Yes II has the Harborside at Atlantis, but you can stay at the Atlantis right now 3 nights 4 days for $399. Staying at the resort is better than next door.
#5 I never said it was impossible to get those locations. I never said you had to trade a top 30 resort to get a top 30 resort. Someone else said cheap traders would get anything in RCI, which also works in II. If it was impossible to exchange for top places, there would be no reason to be in any exchange company.
I said that you got Marriott inventory after Marriott owners took what they wanted. There will be weeks left that are good, but a lot less are available to DVC owners than are available to Marriott owners. Also if you are honest you will never get a 4th of July week at a top 30 beach resort or a New Years week at a Top 30 ski resort by exchanging unless you are incredibly lucky. The best inventory is hard to get in both organizations.
I have II resorts and RCI resorts, and II has never been my favorite choice. I love Marriotts, and I assume I would love 4 seasons and the Royals, but I have always had much better luck getting a week I want, at the time I want, in the location I want, through RCI than I ever had through II. If I want a July week in Florida I can get it at a nice resort (not top 30 but nice). If I want a ski week in Utah in January, I can get it at a nice resort (probably not top 30) through RCI. I feel sure that everyone can't get a prime top 30 week through II anytime they want to either. I want an exchange company for abundant availability at many locations and RCI consistently provides that.
To be honest, if I owned a Marriott or DVC and paid those high MF's, I would never trade one of those weeks for anything to II anyway. I would use it myself, trade internally for Marriott or DVC, or rent it out. I would never give it to II (or RCI) hoping to receive a comparable trade back.
II does have some advantages without question, I just feel that the availability and choices available through RCI makes it the better choice of the two IMO.
