Hey CruiseJunkie2, have you found someone to go with you? I am a female, 27 years old. I was looking at the same cruise (RCCL for a 10 night cruise in the eastern caribbean on the Vision of the Sea). I am assuming the one you were looking at was the Jan 4 to Jan 14 one, the price I'm looking at now is over 1,000 for an outside cabin.
I'd have to double check I could get the time off work though (I have the week of Jan 7th off, it'd just be the 14th I'd need). I am a cruise rookie though, and I have asthma- so I might cough a bit.
