Was at BLT 3 weeks ago, and watched Wishes each of the four nights I was there from the bench in front of the entrance to BLT...the view was terrific and the music was piped in ... I've seen Wishes from inside MK and while I didn't/couldn't see Tink "fly" (the trip wire thing), I found the rest of the show totally comparable.
I thought about going to the TOTWL; also thought about watching from the skyway/walkway...but the view from the ground right in front of BLT entrance was so good (and so empty) that I just stayed put...basically right next to my ground floor villa...it was perfection.
In other words, while TOTWL might offer add'l benefits (food and drink), I question whether the view is any better (at least than it would be from the ground at MK)...so I'd "risk" it if it were me...head over at whatever time you get there after your dinner and if you can't get in (unlikely as that seems based on reports of use of it so far), you won't miss Wishes...
Good luck...
