I have stayed at both Bonnet Creek and Cypress Point Resort and Grande Villas! They are both nice resorts! Bonnet Creek is more upscale, and has some great pools! If you are doing all Disney, then this would be a great choice! If you are doing other things besides Disney then I would vote for Cypress Pointe. Even though it is a little older, it is still a great resort. Alot of the builidings on the Grand villas side have been refurbished with marble counter tops and new carpet (although I didn't have any problems in the old one) This will be my 3rd stay at Cypress in March. I like the grand villas side over the resort side! I have a 2 bdrm rented from an owner on myresortnetwork.com (if you would like his name I can PM you!) we are paying $650 for 13 nights. Last year we paid $625 for a 2 bdrm. Our friends that are coming with us, got a 2 bdrm for 7 nights for $415 in a 2 bdrm, all taxes and fees in!
Really, it depends on what you are doing while you are there! I hated the dreaded traffic outside of Bonnet Creek, but loved the resort. I love Cypress Pointe for it's location and how close it is to walk to all the restaraunts in the area (chili's, giordanos, chevy's, Olive garden, sweet tomatoes, and marconi grill) also, a quick exit out the back is a liquor store, and a winn dixie, and seaworld & aquatica is a 5 min drive out the back entrance as well, or downtown disney out the front. Any more questions, ask away!
