My husband likes to sleep in and I’m someone who hates sitting inside the room while at WDW. I think theme park view is worth it for me because then I can be happy sitting on the balcony still feeling like I’m in the middle of all the action while DH rests. There’s so much to watch from the BLT TPV... castle, sparks from the castle during shows, the train, grand Floridian, buses going to or from MK, the ferry boats, electric light parade, fireworks, people walking, and we could see the CR pool from ours too. It was never boring sitting out there but with the lake view... there isn’t as much to see in my opinion but it is very pretty! If you don’t relax in the room much then lake view.
