Questions about traveling with grandkids

I guess I'm a bad grandmother... We took our 8 YO granddaughter to Royal Gorge, Grand Teton, & Yellowstone last summer. I never gave her any money nor did her parents. I bought her a couple of small items, but I felt the trip was her "souvenir". I did buy her a small camera, & made her a memory book before the trip, made sure she did all the Jr. Ranger programs we could, took her up Beartooth Summit where on the way up she got to see snow for the first time, (she was so excited, although it was a small amount in a ditch, she didn't care!) etc. When we got home she picked out her favorite photos, we got them printed out & put in a small photo album for her. Her parents joined us mid trip & her mom bought her a few things. She never complained!

We also had insurance info & stmt from parents about treatment if need arose. Also got a noterized statement from them that we their permission to have her in our custody, stating she was our granddaughter including all our names. Had her passport for her id.

Wonderful trip!
