Hey Lisa! We love staying at Disney's Caribbean Beach Resort. We just stayed there a few weeks ago and had a wonderful time.
The rooms at Disney's Caribbean Beach Resort do all have mini refrigerators in them. There are no in-room microwaves but there are some at the Food Court that you are able to use. I think that the rooms at Disney's Caribbean Beach Resort seem very roomy. I've read reports where they are a little over 300 square feet. When we stayed at Disney's Caribbean Beach Resort, we had 3 adults and 1 child in the room. While we weren't in the room for long, we never felt cramped.
If you call
Disney's Caribbean Beach Resort during normal business hours, they will be able to connect you to the Marina for more information regarding boat rental pricing. Click the link above and look to the right hand side of the screen, there you will find the phone number for the resort.
If you decide to check out Disney's Caribbean Beach Resort on your next vacation, I hope you have a great time. We love the resort and all it has to offer. Make sure to relax in one of the hammock for at least 5 minutes, it is wonderful! Happy planning!
