3 girlfriends and myself are planning a cruise to celebrate turning 50. I was thinking 2 interior rooms. however one of the girls says I need daylight to wake up an alarm won't be enough for me. So now we are looking at all four of us staying in a balcony room on the valor. We are on a tight budget. They know someone will have to sleep on a upper. I am not ok on s bunk and made that clear but 2 of the other 3 are ok with that and are going to work it out between the two of them. I am pretty low maintainance. Is this doable. we are planing on driving from stl to nolo.
