I have rented a locker at MK before.
I carry alot of junk, change of clothes, dd's costume, etc... and I dont want to lug it all around in my backpack, my shoulders KILL at the end of the day!
I do the $7.00 lockers and they are fine, and you get the $2 back.
I think it's well worth it than to have sore shoulders/neck/back!!
Ohhh!! I rented also at TL.
there you have no choice, you need to store your stuff somewhere to go on the rides. It was the same deal I believe.
They also rent towels there if you dont want to lug a wet towel home.
