BLT fireworks July 3 and 4

[anneeb]

This morning I snagged a BLT 2 bedroom preferred view room for July 3-July 5. I have never been to WDW for 4th of July and don't know what to expect for fireworks viewing. Am I remembering correctly that Top of the World Lounge/Villains Lair will be open just to those staying at BLT on points with DVC direct benefits (all criteria we meet). Has anyone done this viewing and is it a madhouse? How early do you need to get there etc? Thanks!
