Weird question…best group alcohol for a beach trip? Details below.

I don’t usually drink but I’m going on a trip to the beach with 6 people total. We had the idea to get our drink on at the beach.

My question as a non-common drinker is:

What is the best drink for a group of people at the beach? We generally just want to have a good time (even though it’s possible with drinks) and laugh our asses off.

A pack or big bottle for a casual setting would be best.
