Personally, I think the fireworks and Tree of Life come ons are a bit much...First of all you are at least 3 miles from the fireworks, and there are lots and lots of buildings and trees in between. I know you can see the fireworks from hwy 27 north of 192 but now you are 5 miles away and they kind of lose thier luster a bit...
These 3 developements all have new high end homes, and there is very little difference in quality...The 2 main differences will be the quality of furniture, electronics, game rooms, bed sizes in the houses. Also homes with gas heat will guarantee warm pool and spa during rare very cold times...
second big difference is amenities. I am not aware that Indian Creek has a clubhouse with big heated pool and hot tub, game room, workout room and so on. I know Windsor Palms and EI both have club house. I think
Windsor Palms is bit more decadent with pool tables, larger pool etc....
If you are choosing between these 3, I would look at what's in the home more than which developement as they are all very nice and about equal distance to Disney...
