What is your favorite vacation drink?

And yes,

Just back from Aruba. What a great island.
This time we stay at Renaissance, Oranjestad.
I think the best hotel in Aruba, but that's my opinion. Why? They have the Blue Bar.
The Blue Bar is a trendy bar at the pool of this hotel. The atmosphere is great and they serve the best cocktails. My personal favorite is the Mud Slide. But just the regular Pina Colada is also so good.
Now I am curious, What is your favorite vacation drink?

I also just came back from Aruba and consumed my share of drinks poolside. My favorites would have to be the pina colada or a mojito. For some reason those two always hit the spot on a hot Aruba day!
