Marco,
Sounds like a wonderful trip. Your 17 year old son and wife may enjoy Jackson Wyoming which is the town just south of Tetons. Lots of shopping, restaurants and nightlife type things to do there. Pricy but lots of shopping and eating type stuff if they enjoy that.
I don't have a whole lot to suggest other than what has already been posted. Oner thing I will say is don't overlook some short hiking opportunities. 3-5 mile ( 5-7km) hikes are plentiful in both Yellowstone and Tetons. Most tourists never leave the comfort of their automobiles so you will find less crowds on the trails especially when you get a couple Km away from the trail heads.
Beautiful landscape opportunities in both parks. The mountains in Tetons are majestic.
As for the crowds, that's just part of the experience. If you take it as just something to deal with and don't get overly anxious then all will be fine. Someone suggested checking the road closures and construction (should be available on the National Parks website (https://www.nps.gov/yell/index.htm). Also, the ranger stations at the entrances to the park will have the most up to date info. Also, don't get too caught up on "being a tourist" (everyone else there is too).
I hope you and your family have a wonderful time and enjoy your trip.
Jeff
