We are off to Bali for our fourth time in March, but this time with our two boys, one aged 4 and the other turning 8 whilst we are there. We are thinking of taking them to Waterbom Park as we haven't been there yet. Firstly how much does it cost to get in per person and per family and secondly is there a height restriction on all of the slides as obviously the kids aren't all that tall. Also are adults able to be in the kiddy area with their kids?
