We have been owners since 1999. Every contract that we have had has the annual increase in it. One of ours had 3%, but the others have had 5%. They will not change that. Pretty much all timeshare contracts have that in them. We have progressed up to two Grand Luxxe units and have had as many as 5 contacts for 6 registered weeks of use for MP & GM units. (I bought most of the MP units on Ebay cheap.)
The sales force at both RM and NV are extremely brutal. It does not matter where you buy - you do not have to buy in NV to go there and you will not get any preference because you did buy there. You just have to own at the level (or higher) where you want to stay. At the moment, only RM & NV have Grand Luxxe. NV has more units than RM. Acapulco is opening a GL building sometime this spring and Puerto Penasco says they are converting a building they have never finished into a GL. The Cabo location has renovated a few units on the 6th floor and call them GL, but from the pictures I have seen, they are just super upgraded GM with a much smaller kitchen and a weird layout - I would rather have the GM than that.
We have been to all the locations at MP, GM, GB, and GL levels over the years and each has its own ambiance. We are not excited about the Vidanta World, because that will make the rest of the resort so crowded. We liked it better when it was not so large.
We will take the family to NV next year to see if they like it. They have not been since 2008. When it is just the 2 of us, we may use our weeks at the PV MP Marina location where we can stay 2 weeks for one GL week. Our family loves PV and therefore, our Buganvilias is their place of choice because they can get out and about easily. They have liked the Marina location because of that.
