It was clean (everything is brand new), staff were nice and friendly. It was very hot when we went but its an outdoor park and you get what you get. 90% of the rides were open. There are few carnival games dotted around to. Mini land was great but as another reviewer mentioned, there was no signage up so it would have been nice to know more about the builds.
There are not a lot of rides, it felt like there were more shops and food then rides. There are even less for bigger kids (8+). the Rides are also small and short, not many riders at once so I imagine the lines will be ridiculous when in full swing..
My daughter loves Lego and she did enjoy herself but we didn't have to pull away when we said it was time to go.
All in all its overpriced. We did the entire park in 3 hours and I can't imagine anyone traveling and staying there overnight for that. They will need to beef it up or I doubt they will be open in a few years.
