Can you skype your besties, and have a virtual party? Could be a laugh ... you could each have some drinks (non alcoholic if that's your preference), something for dinner - you could even watch the same movie at the same time.

A friend of mine live in another country from her bestie, and they skype-movie-date all the time

Personally, I had a karaoke bash. It was worlds of fun - but not the sort of thing everyone gets into
