Throwing a party for a friend can be something simple or more involved, depending on what you want to do. For example, if you guys usually do parties at home, maybe this year you can throw him a party in a party bus nyc. This is a cool way to spend the night out and about. It is basically a club that you can rove around town in with a professional driver. There are a few things that make it so cool. The first is that the novelty alone is worth the price of admission. Second, you do not have to worry about a designated driver. Now, I suggest also getting a hotel room so that you guys can just end up there and keep the party going. Hotel rooms can also feel like getting a vacation even though you are staying in town. Have a great time, and as always, be safe.
