I stayed there 3 years ago and enjoyed it. The rooms were nicely furnished and refurb-ed probably 4 years ago, three very good restaurants, good pool. You have a choice of rooms with exterior view with no balcony or an interior view with balcony opening to the atrium. The lobby and restaurants were renovated in 2007.
It is right across the street from Sea World. While I don't have any personal experience using the bus service (either Lynx or the contracted service), there is a Lynx bus stop right in front of the hotel.
If you rent a car, the hotel is about a two-block drive off of International Drive. There can be a lot of traffic around those two blocks especially at closing time. My tip is to not use International Dr but to turn right onto Westwood Dr, which takes you under I-4 and is a good back road to Rt 535. It comes out just above the Crossroads, which is very close to Downtown Disney.
