I'm of the 'why can't people just go to the pool where they're staying?' frame of mind. i guess if a pool is the main attraction, I would just stay where I wanted and get a water parks pass. With the Fort, it's just too easy for locals to use. It's not other resort guests that are the issue. I just think magic band access makes the most sense but maybe in a bit, all the resorts will have them. From a purely CYA or liability point of view, it is probably best for Disney if they can make sure only guests are using the pool. Ah well, in time perhaps, I rarely go when it's really busy but for those who go on weekends or during the summer, just a few extra, non-resort guests can add up.
