We didn't ask for it. He is a multimillionaire and gives all of his kids (7) money all of the time. On the check he wrote "for whatever", lol. We definitely do not need it but it's appreciated. We just put it right into a savings account, it's not a lot of money at all.
If you didn't need it why would he send it?
Anyways, OP, I'd go to Disneyland for a couple days and stay in the Grand Californian or whatever the hotel is called.
My FIL just sent us a 2,000 dollar check just because. We don't think anything of it, it's really not a lot of money. We just threw it into an account.
