Wow!
Wow! WOW!
Robyn, I cannot imagine that you will not LOVE staying in that 4BR Presidential Suite! Whooooeeee! Take a look at the online
photos. The very nicest photos shown are of that 4BR suite. Here's the website for
Fairfield - if it doesn't come up at the resort, select Florida in the "Resort Search" and then Bonnet Creek. They have photos and video streams to show you what is there.
The only thing that feels like it's offsite to me is the infrequency of bus shuttles. However, if you plan to drive and only use that shuttle on occasion, it'll be a non-issue. BTW, it's no small number of Fairfield points to reserve that baby - your parents are quite generous in providing it!
Getting back to the resort midday is as easy (if you drive) as getting back to the Caribbean Beach Resort (follow the same signs), since it's right next door. Guests at these two resorts can actually see one another's rooftops above the trees - that's how close they are! (You cannot walk between them, though.)
There is currently limited food at Bonnet Creek - a poolside Bar & Grille is all, with fairly limited hours. But it's only a mile or less in either direction to drive to Downtown Disney's restaurants or the Epcot Resort's restaurants and another mile past DD to the Crossroads area of Lake Buena Vista. Since it's easier to drive between Disney resorts than to use Disney buses, you'll probably find that you are just as likely to sample Disney restaurants as if you stayed onsite. With a full gourmet kitchen, have a few goodies handy so you can get whatever you want, when you want.
There's a lovely, large, zero-entry pool, a small floating river and a kid's water spray play area. The views on the lakeside include the lake and pool/recreation area. On the outside, views may include parking lots and treetops but they mostly look beyond to the top of Epcot's ball and fireworks. Ask your parents to ask the front desk what their view will be - it's usually preassigned.
You didn't ask but the resort also offers a nice billiards room, a small fitness room, a computer for guest use, an activity room and inroom internet access for your laptop. Outside, they have a simple mini-putt-putt. The staff are super helpful and friendly, IMHO.
My, my - I can tell you that my DH and kids would clobber me if we didn't take the offer you've been given. LOL!

You won't regret it - HAVE FUN!!!
