Everyone has their favorite but, IMO I really don't think it matters all that much. Kingfish would be my least favorite.
There's a couple of things I don't like about Kingfish.
1. It's detached from the main complex. Yes it's mostly self contained but you're quite a distance from the Marketplace, Starbucks Express and Pizza Hut Express. It has it's own fitness center, bar, pool, hot tub and gas grills so it's not so bad. If you want a little more isolation of the feeling of a smaller resort but it might be the best place to b.
2. Room enterances appear to be outside rather than interior hallways. Not a problem on sunny days but if there's a little wind and it's raining it could be an issue.
On the plus side a majority of the rooms should have some sort of water veiw. South facing rooms will have good views of the inlet and of boats coming and going. East facing rooms would be ocean front. * south facing rooms are considered ocean front by the resort but not by many of the owners.*
Sailfish and Dolphin are closest to the front desk, MAZE, Marketplace, Starbucks Express and Pizza Hut Express. They are also closest to the free form pools that seem to be favored by families with children. Sailfish is closest to the kiddie splash pool.
Foilage seems to be taller in front of Sailfish vs Dolphin. The palm trees in front of sailfish reach up to the 4th floor and tend to block some of the view. We were recently in a 5th floor room in Sailfish and were just above the palm tree's. Any lower and the view wouldn't have been as good. Dolphin might provide a slightly better view if you're on a lower floor.
Cobia and Pampano are closer to the fitness center and the Cobia pool, which seems to be favored by adults. The Cobia pool also has adult only hours in the morning and has the adult water arobics class in the morning. Foliege isn't as tall in front of these buildings and provide slightly better views for lower floor rooms. Pompano is a decent walk to get to the Tiki Bar/Grill, Market Place, Starbucks Express and Pizza Hut Express. On the other hand, the only compition for a view looking south is the big pink building (low rise condo's) and if you can snag a higher floor you'll have a decent view looking south from an ocean view unit. If you're on a lower floor you might be stuck with a direct view of the pink building, which I find unattractive.
We've generally prefered to be in Sailfish or Dolphin because I like being close to the Marketplace and Starbucks express. I think next time we might request to be in Cobia for a change of view and to be closer to the Cobia pool and it's adult only hours. One other note, the hot tub by the Cobia pool is *suppose* to be adult only. When I'm enjoying a soak in a hot tub, the last thing I want is chilren playing and splashing water with their parents.
To request a certain location you'll want to call the resort 2 weeks before your arrival. I believe room assignments are made 1 week prior to arrival. For us almost anywhere is acceptable as we really like the warm weather, the beach and the resort feel of this timeshare. It's the one place my wife wants to go to every year.
