Colter Bay is a super nice park! Make reservations early. We were there for 4 nights 2 years ago and wished we had longer! We enjoyed biking around the cg and rented a canoe one day. Location is perfect for the Tetons. If you haven't been to the Tetons before I would suggest you plan more time there than you think you will need. It is definitely smaller than Yellowstone, by far, but there are so many great hikes and drives. Also, it is a beautiful drive down to Jackson (white water rafting on the Snake). Don't miss Inspiration Point and if you have a 4x4 there are incredible trails down to the river.
