seabourn has 7 night caribbean from ~$2700 and 12 night transatlantic from $2500. (only $200 single supp on transatlantic)
seadream has 5 night caribbean from $2000 and 11 night transatlantic from $2200.
small ships like seabourn and seadream are probably not the best for a DO, unless you did a charter. which would require a LOT of people.
cunard, celebrity, etc would start MUCH cheaper, and seem to be much more workable IMO.
(i thought seabourn was fantastic, i did a crossing last year for my first cruise. the small size and having all regular pax just seems to be a minus for a DO.)
Have you read Omni lately?
heh, i guess i count as young and mature
i actually had admin remove OMNI from my account, as well as starwood.
