I'm doing A High School Musical themed birthday party for my 28th birthday.

My actual birthday is Wednesday, March 18th, but I'm doing my party on Friday, March 20th. I'm doing High School Musical theme for it and gonna have decorations and High School Musical songs playing and my friends and guests are dressing like the characters ❤️ I'm gonna cosplay Ryan for it since he's my favorite character❤️

Any extra tips on how to make it better?
