we have golfed with kids @ Oak Trail. I think they will let your 7 yr old "golf." They have Jr clubs for kids for free. It is A LOT of walking--no carts. I think Dad should take 7 yr old and golf a couple 4 or 5 holes, then call it a day. I think at the 4th hole, you are near enough to walk back. My 8 yr old was very tired after 9 holes. My 13 yr old quit after 4 holes. It's a great "big" course for a kid to learn on--lots of amateurs--no pressure---but be sure no one wears denim. They also have a driving range that you can use prior/after golf right at the starter place.
IMHO, it's not worth the $$$ to put kids in the kids club to golf @ Oak trail. Since it's free on your PAP--you could also pop over and golf 4 or 5 holes another day as well while kids were in the pools with 1 parent. Also, for the parent who stays with the kids--a fun, low key thing that I love when I am alone with my kids is to go to the Community Hall and have then do crafts/color, etc. It's like a kids club, but open 8-8, but parents have to stay. It's free. The AKV Community Hall is the best one, IMHO. It's over at Kidani. Lots of free or $1 crafts all day, Wii, PS3, pool table, games. There's a great balcony to sit and watch animals, etc. My kids will stay for 3 hours there.
