Literally having this debate!!
I’m thinking about doing TL, never been. I did BB on Sun (split-stay) and arrived at 10:20am- oof! It seemed quite busy. I think it was 10 mins just to get in the park. I wanted to try the chair lift because I’d never done it and had read the wait gets long, it was about 20 mins. Up top a 20-30 min wait for the main raft slide, which was rather boring honestly. Sick of standing in sun I hit the lazy river which was nice but I got out pretty quick as I knew I needed to get my lunch order in. Glad I did, it surged in business not too long after that and when I tried to do the lazy river again after lunch it was miserably busy. To top it off you can’t read a book in the lounge chairs as the backs don’t move, and I had planned on doing that for my afternoon.
Overall, it was my first water park experience at Disney and all it did was make me wanna go to VB hahaha (8:30am entry with EE there!). So, I’m debating leisure park morning or quick TL trip? Both would have me at SAB by lunch as I’ll need an afternoon off my feet.
