Going there during summer is the best, as you WILL GET SOAKED. They provide you with a disposable poncho, long enough to cover from head to almost my knees, I am 5'8.

Absolutely critical to hang on to your little ones, and sitting down will be an absolute bad choice as all seats will be soaking wet, and your pants will be the sponge.
