They Shut the Place Down

“A few days after a birthday celebration for my daughter, we are still talking about the fun that the little ones had on this day.  They shut the place down and the place is yours for the duration of the party. The guests started arriving and you could see the joy and excitement on all the kids faces.  From station to station, they were all smiles.  There were even a few adults that looked like they were having just as much fun.  Prices are reasonable, little kid parties held here are perfect, and short of Disneyland, this is probably the most fun they will/have had in a long time. Good job!”

Best Party Ever!

“Best party ever!  Very reasonable price for a birthday party.  The stand-out for this place is its cleanliness. It’s awesome. As you arrive, they help you unload your food, cake and decorations. Every part of the kitchen, tables, play structure is perfectly clean. There are plenty of toys for all ages – again all spotlessly clean. I enjoyed the fact that for 2 year olds you didn’t have to worry that they would get bull-dozed down by the big, older kids running around. It’s ideal for the 0-4 or even 5 year olds.  Congratulations on a great local business that should continue to be a fabulous place for play and/or parties.”

We Were Very, Very, Very Impressed

“We have gone to Diddalidoo on several occasions for open play time.  My daughter has always enjoyed it and its a nice alternative to a park on cold days.  The staff is always very friendly and the place is quite clean.  I decided to have my daughter’s 3rd birthday party at Diddalidoo.  The price point seemed to be consistent with some of the other party place options in the area.  We were very, very, very impressed with how the party went.  The staff was very accommodating and was nice enough to let us drop off most of the party supplies the night before. This eliminated a lot of the “morning of” stress and made it less likely that I would forget something.  They also had all of the tables set up and decorated with the things I had dropped off when we arrived the next morning. They allow you to bring your own food in-which is nice as well.  It was so great!  I highly recommend this place for your child’s party.  The kids ALL had a blast (ages months to 7) and it was fun for all.  Clean up was quick and easy as the staff helped with this as well.  We didn’t feel rushed out of the place, as I had noticed when attending other b-day party’s at some of the kid friendly spots on the peninsula.”
