I had my daughter's birthday party planned for over a month. She was very excited. I had the cake, balloons party favors packed in the car ready to go and my phone rang. It was 321 bounce calling to tell me that they had been having electrical issues all day and could not host the party. This was one hour prior to party time! If they had been having these issues all day why did they wait until 2:30 to call me when the party was scheduled for 3:30? Needless to say I had a very upset 8 year old. I had to scramble to call everyone, try and make other party arrangements and calm my daughter all at once. Do these people know what this kind of thing means to a child? If you have electrical problems fine, not your fault. It is your fault when you fail to call and warn the parents at a decent time in order to allow them to make other plans and not waist money on cake, balloons etc.
We ended up having the party at Pump it up in Kirkland later that evening. I was told by them the same thing happened to another client that had a birthday planned at 321 bounce that day but they received a cancellation phone call at 9 am for an 11 am party. This proved to me that 321 bounce knew about the electrical problem much earlier in the day but decided that waiting to call an hour before my party was to begin was good business practice. I don't think so.
They did refund my deposit but did not offer anything else. I lost money on party favors because not as many kid's could come at the later time, I also wound up spending more money at pump it up. The staff was not very sympathetic at the time of the phone call. They seemed "put out" that I was so upset. I basically got the equivalent of "Like, I'm sorry okay".
I don't know what electrical system there hooked up to but if you choose to plan a party there make sure you call that day to make sure they have power or you might be sorry!
