Kids' birthday parties are getting more expensive, according to a new survey.
We want to know about the best birthday party you've ever been to.
What made it so fun? Was it a great themed party? Did a DJ play some cool tunes?
Maybe you went out to a theme park?
Tell us your stories, even ones about the worst parties you've been to as well!

My worst party was about a year ago. I planned a disco and invited the whole year but my dad insisted on inviting my grandparents round too and they shouted when they caught me dancing with my boyfriend!

I don't have to go out for my birthday parties because we have a swimming pool in our back garden and my dad does a BBQ, it's wicked!

I had a huge party in a theme park - there were quite a lot of my friends there and we had so much fun going on the rides.

I once went to pleasure wood hills (near Lowestoft I think?) for my 11th birthday and for my 12th I went go-carting, it was really cool!

My 13th was the best 'cause I had a barbecue and hired a bouncy castle at my house and me and loads of my mates mucked about and it made it even more fun when it rained and we got soaked in my garden! Some people didn't find it as funny as others though!

About two weeks ago my friend had a really good sleepover party, where we made a video about a gymnastics competition. It was brilliant and the eight of us are all getting copies!

Definitely my 10th b-day I was in America in Florida. I went to Disneyland then swam with the dolphins - it was well good I wish I could repeat it again!
Roxy, 13, Southend on Sea
My best party was my mates as she was blowing out her candles on her cake, and after her mum had removed the candles she was looking at her cake really closely and we smacked her face into it! She didn't mind though. It was really funny.

I had a really groovy party with my best bud! As her birthday is 6 days after mine we had a joint party. It was really fun 'cause about 30 people came. I recently went to my friends party and he had a trampoline, two bouncy castles and an inflatable slide. We played loads of games on the slide and I really enjoyed it!

One party we had we watched a movie, roasted marshmallows, and then slept outside in a tent...it was great but nobody could really sleep. :)

I had a party at the town castle and it was amazing, you'd think it was boring but it was really fun. We dressed up and chased around and it was great.
Harriet, 11, Stafford
My friend took me and 3 others to Disneyland Paris for the day! And the year before we went to Cadbury World! But it doesn't matter what you do as long as you have a good time.

The best party I've been to was when my friend's mum hired a limo, and we went back to my mates house and we just watched films, went in her spa and had loadsa fun!
Claire, 14, Derbyshire
When me and my friends were younger we always wanted a big party with loads of people. Now I don't feel hyped up about my birthday, usually I invite 5 max of my closest friends and we go to the cinema or bowling and to dinner.
Alexandra, 14, Madrid
My best birthday party was a surprise. It was my 13th birthday and my friends randomly walked right up to my door with me. It was only then that I noticed the balloon. It was great we played loads of games and had a cool time!
Marie, 15, Cheltenham
For my birthday me and four friends went to a place called Llangrannog for 4 days and we did loads of really cool stuff like quad biking and went to the beach.

The best birthday I've ever had was my 6th birthday when my mum decided to invite everybody from my school. We had one-legged races, treasure hunts, and all kinds of games. Now my birthdays are never fun though. I think the fun goes more and more the older I get.

On my sister's birthday my mum told me to check on my sister's cake which was in the oven. I walked in, looked in the oven window and there was nothing there. My mom shouted at me for telling ''lies'' - she went and looked and the cake EXPLODED!!!!
Lee, 13, Birmingham

For my 13th me and 2 of my friends went to a local gig. We got sweaty, soaked with water and completely did our legs in - it was awesome!

I went to my friend's party once it was really cool, we went swimming, and there was a bouncy castle back at her house so we went on that. And later we had a disco, watched the haunted mansion. And then there was a sleepover and we ate the rest of the food from the disco!!!!
