I was amazed at how big the resort was. My children enjoyed the waterparks and I wish we had more time to spend there.
We spent a beautiful day at the outdoor park at Glacier Canyon. I thought there was just enough things to keep my 9, 5, 3, and 1 year old entertained.
I was upset and quite irritated when I was on a double tube on the river with my 3 and 5 year old. We got in line to go down the slide and when it was our turn to go down I was told by the lifeguard only 2 people. So I had to jump out of the tube with my 3 year old and my 5 year old went down the slide by herself. Yes, all three of us could have gotten out of the tube but my 5 year old was very excited and the guard sent her down.
I read the river rules and nothing is posted about only 2 people and if only 2 people are suppose to go down the slide then why did the other lifeguard let us get in line. The rules also say that children should be accompanied by an adult. So wasn't sending my 5 year old by herself a violation of the rules. I was then worried about what my kid was going to do when she got to the bottom of the slide while I rushed around, with my 3 year old in tow, trying to find her. I would have appreciated some consistency with lifeguards and the rules. I'm not sure what it would have hurt to let the 3 of us go down the slide.
