You do get a daily kids club session included in your room price though.
Undercover secure parking is $10 a day. If you want to park in the open air car park then that is free.
I don't find the rooms too small. I always book Paradise Resort when it's on sale so I think it's very good value.
I think you'll find Turtle Beach won't allow visitors guests to use their facilities either. Makes sense to me. I pay to stay at the resort, so why should other visitors guests get to use it for free?
