Sail away drinks for RCI are fruity type coladas.. My favorite was Mango tango- a mango colada.. Mmmm yummy! I had about 15 during my cruise! lol .. and of course a Pina colada!
They always come in the souvenir glass, so maybe it would be cheaper in a regular glass. Drinks of the day are usually listed in your compass. Priced about $4.99 each, with rum is I think $5.99... i think? you must ask for them with rum or it will be a virgin. I was always asked prior, with rum or no? But i hear a lot of people say it was inconsistent.. they thought they were drinking rum, waiting to get buzzed and realized 10 drinks later that they were all virgins!!! So just be sure to ask if thats what you want, just to be safe!!
Stumbling home to your cabin is acceptable, falling over board is not- drink responsibly! lol
