I like Bldgs 50, 51, & 52. They face the lake; you can see the Sea World fireworks from the screened in porch; and the porch does not get afternoon sun - therefore it is pleasant to sit on the porch in the afternoon/evening.
They are very close to the entrance, and short walk to the Clubhouse
52 is closest to Clubhouse,
50 is closest to front gate).
Across the lake, units 63, 64, 65 are also nice, but
1) much farther from the entrance - lots of speed bumps
2) get afternoon sun on the porch
65 is closest to the Island Pool (might hear noise)
63 is closest to the Activities Center (take boat across to Clubhouse, rent a boat, play basketball, shuffleboard, pingpong & arcade).
