HELP!! I need ideas🙌🏼🙌🏼

My boyfriend turns the big 3-0 in May, I know I still have a long way to go but I’m more of a I want a plan now person lol so I am having a party here at the house the day before his birthday bc it actually falls on a Sunday this year, something for all his friends and family to come to. BUT I also want to take him on a vacation, fly out the day of his birthday and either make it a long weekend trip or a week long trip. He loves the beach, so something beach front is preferred, if anyone has any ideas or recommendations please let me know!
