I am going on my first cruise (longer than one day) with my girlfriend and 2 friends (1 guy, 1 girl). We are booked on the Voyager of the Seas for next May. Right now we have a D6 outside stateroom but was thinking of upgrading to a "C" class suite. I know space is tight but is it worth the extra $$?
We had a D7 cabin on Explorer and while it was just fine for the 2 of us, the only problem I can see is all 4 of you sharing one small bathroom. There is plenty of space to unpack and the luggage does fit under the bed easily, if you can arrange some kind of schedule for the bathroom, you should be fine. These cabins were actually one of the nicest cabins we've had yet on a cruise. You all will really have a blast on Explorer.
