Please share a link to the Orange Lake info you found.
WBC: I can only speak for this resort from experience. Activities for kids and adults are all over the place. There is something going on almost all the time. Ducky races in the lazy rivers, games at the bigger pools, karaoke, crafts. There were more but we didn't get to do much of it.
Windsor Hills: Seriously looking at staying there. The condos and townhouses are great. The one drawback I am seeing so far is that there are not too many planned kid activities. There are some, but not nearly as many as WBC. I have quotes for the second busiest times of the year for between $550 for a 3BR condo all the way up to $1,000 for 3BR townhouses. Several of the townhouses are quite a bit less than $1,000. They have a little dipping pool if the kids or adults want to just hop in and get wet.
Orange Lake: Waiting to see quotes to see if it is worth looking at. From the pictures and amenities, it looks as good as WBC...dare I say better just from looking at pictures and reading reviews? I will hold that judgement off for now. Vacation Strategy rents OLR. They have a pretty wicked aerial picture of the resort with Everest, Swan/Dolphin, Epcot in the background.
All I can say for certain is that we will always be AP and offsite family. When I run the numbers, I can get 3 weeks of trips for the price of 1 in equal accommodations on Disney property.
