I remember the good old days when the Chessington Hotel was a Holiday Inn. Every time I stayed I used the pool and it was nice and relaxing. Then one day Merlin ripped out part of the bar to install the Savannah Splash Pool... I tried the pool a couple of times subsequently but it was always packed. You couldn't swim properly anymore as there were kids jumping in from all sides and people just messing about across the whole width of the pool. There was not even a dedicated lane for people who wanted to use the swimming pool to, you know, swim. Just a melee.
If this water park is going to be oversubscribed anything like the Savannah Splash Pool then it will be anything but "chillaxing".
