My Birthday is coming up

How do I ask the family group chat nicely if they'd like to pitch in for me to celebrate my birthday at Disneyland. I'm 31 years old. Yes, I have a job. A little help even a couple bucks would help. I'm trying to go alone so I don't have to worry about anyone else as a lone rider.

In the past I've thrown huge birthday parties for myself and haven't thrown a big one in a couple years. It cost a lot then but I'd usually prep months in advance.

Just asking for genuine advice. Thanks.
