Pools -
I think the Congress Park pool is the prettier one with the great view of DTD. It's usually not overcrowded.
The Grandstand pool has the attached kid's waterspray area so that is fun if you have little ones. As well, there is a pool bar, and I think a drink refill station.
Both are great. AS for us, we don't spend much time at main pools as our kids are older so I don't have any experience with the main pool.
Spa -
Don't forget the spa! This, for us, is one of the biggest attractions of SSR. We head there everyday, either for a work-out and steam/sauna or just the steam/sauna. It's wonderful, especially if you have spent a lot of time in the sun and your 'northern' skin is complaining !
Turf Club and Artist's Palette -
Both are great. Love the variety of food, always tastes fresh. The CS restaurant has an odd configuation as the gift shop is also right there, but not really a big deal.
Community Hall -
Lots of activities and great CM's. We have rented bikes for pedalling around the resort, kids have taken craft sessions, played ping-pong and video games.
DTD -
Nice to be close to DTD. We have teenagers so they like to spread their wings and hang out on their own for some of each day. They prefer SSR to OKW for this even though OKW is also close to DTD. Now that PI clubs are closing, I will feel better about them going during the evening hours.
