You would like either one of those, so no worries. What we enjoyed about each when our kids were younger:
CR: watching the monorail go through the resort, enjoying many meals at Chef Mickeys, and we took full advantage of the walkway to MK. Even though the monorail is convenient with a double stroller (which I assume you'll have, and also what we always had), it's even more convenient to simply walk back and forth to MK.
GF: Simply put, we enjoy every aspect of GF and it's one of our favorites. Has a great kids' splash area and beach pool. Love the main building, lobby, and shops.
With 3 boys, I'd almost be inclined to vote for CR. But in the end, I'd probably go with the lower price which very well may be GF with a discount.
Have fun!
