Surprise Party...

My husband and I are currently in Costa Rica, getting his visa to come back to the states legal. He hasn't been to his home in Costa Rica in 15 years.

We will be coming home this week. I want to plan a surprise welcome home party for when we get back home.

We will have a private party room/hall

I am going to have it catered with alcohol.

Id like to do something special for him, I just don't know what!

Any advise is very appreciated as I've never done a surprise party before. I want it to be epic. Thanks in advance!!
