This is the wrong part of this site for this question -When you redirect dont forget to tell them what cruise line !!!!!!!!!!!!!! All cruises is rediculous.
Someone new to this site and using Answers for the first time might well be forgiven for believing that they could aske this sort of quesion here.
Still, good of Stone of Oxford to provide the answer the questioner was looking for.
Crystal ball is working well today, think question may refer to Transocean 'Marco Polo'cruise 22 June 2009, this ship does have single cabins. Check availability by looking at offers at the top of this page. Apologies if I've got the wrong cruise, as the aforementioned information will be of no use whatsoever!
