$400 could get you 3 moonbounce with us for the whole day! I honestly think your child would truly enjoy a private party with their friends with a couple of bouncy castle all to themselves.....
besides after the 2 hour party, what do you do with the rest of your day, it's your little kids birthday, do you just tell them that you just had their party, birthday's over? I think not, he/she is gonna want to celebrate all day.
Enjoy bouncing with us for a third (1/3) of the price.
