I have lived in AZ for 30 years and remember going to big surf as a kid. I don't think they have made any upgrades since my spring break trip in 1994. There were very few slides and not a lot of seating. The wave pool is still big but other than that not much to brag about at big surf. We were disappointed and will not be back. Wet and wild and sunsplash are a much better value and have more to do.
