We stayed at the Homewood Suites in Lake Buena Vista about
18 months ago. In other locations (not FL) we've also stayed at Sierra Suites and AmeriSuites (across from USF/IOA). We liked Homewood Suites better than the others. Unlike Sierra and AmeriSuites, the one bedroom unit at HS offers much better room separation. The entry room is a combo kitchenette (with full size refrigerator, microwave, coffee maker, toaster and stovetop range) and living area with a sleep sofa, recliner and it's own TV/VCR. The bedroom is completely separate (it has a real door to close it off from the living area). The bathroom is located off the bedroom area. We had a unit with 2 full size beds.
The Deluxe Continental breakfast at this hotel was one of the better ones we've had in that they also had some hot items such as scrambled eggs and breakfast meat (some days bacon, other days sausage). Overall we were very pleased with this Homewood Suites. I've seen some posts on the other Disney area Homewood Suites that indicated that they might not be quite as good as the LBV location. You may want to do a search
on that.
We also liked the location of this HS because it's right on Palm
Parkway which obviously has excellent proximity to WDW but also
allows you to get to USF/IOA without getting on I-4. Very convenient!
JMHO--good luck with your choice.
