Hello beach bums

I'm checking in to CBR for my first trip to WDW on Saturday evening, and I've got two questions for you.
1- what's the grocery delivery situation? Who do I call/order with, and how does everything show up in my room? Do I need to be present to accept delivery?
2- what are the hours that the pools are open? We arrive at MCO in the early evening and probably won't make it to the hotel until 7:30 or so. I'd love to be able to promise a swim to my kids as a reward for a long plane ride from California.
3- my son wants to know if you can watch the outdoor movies from the pool while swimming. So I'll just ask you
Thanks in advance!
