We have stayed at the HGVC @ Sea World twice, once in April of 06 and again in April of 07, and have another upcoming reservation in September of 07. On the April trips, we were there for 12 days each time. In September of 06 we stayed at the International Drive one, it was nice, but we chose to go back to the Sea World location, just seems there is more to do there and more to choose from, as far as pools go, etc.
I have absolutely no complaints about this location. The rooms were very clean and spacious and well stocked with whatever you need. The staff was friendly and accommodating. There are a number of pools/hot tubs to choose from. Lots of activities also, indoor movie theater, etc. The only drawback might be if you get stuck in a building that is not as close to the main pool area. On our first stay, we were put in a building at the far end of the property, so the walk was a little long for my husband, who had knee replacement, and it was just a pain to have to drive to the main area every time we wanted to go there, so we asked to be moved to a building by the pool, and they happily accommodated us.
If you haven't already done so, go to the link below on tripadvisor website and check out the photos (hotel and candid traveler photos and virtual tour). What you see is an accurate depiction of that property.

I would love to stay at a Disney Resort some day, but room (space) and cost wise, this resort makes much more sense for our family.
I hope you have a good stay there!
Another link to check out is the hgvc website for that location. If you click on the link on that page that says Grand Scapes activities, it brings up their schedule for the month, to give you an idea of the types of activities they offer.
