Single cabins are quite rare on most cruise ships. Your local TA should have some ideas. However, single supplements are probably not your first priority. Consider the age group catered for. I would guess that you would not like a huge 'family' orientated ship with loads of kids. Perhaps a smaller, more friendly ship with fixed dining so you know who you'll be meeting at dinner. Also staff who know your name by the end of the second day! There is always the option of 'sharing', but I don't think I would be happy sleeping with a complete stranger (unlessit was George Clooney!)
Whatever you decide, have a wonderful holiday and please review it for other single travellers.
Http://www.cruise-network.com/singles.html?gclid=CNjf1fin4JQCFQuJ1Qod43GKSQ This link takes you to a website which lists most of the cruise companies and advises the ones that charge less than 50% for a sinlges booking. Where there is no indication on the list then the supplement is over 50%, hope this helps.
Most cruise lines add on a hefty single person supplement even those which have cabins designated for single occupency, however,there are ways of avoiding this some of these costs. If you are able to travel outside the peak season and can book at the last minute (particularly pre and post Christmas) many cruise lines will significantly reduce single occupency supplements in order to fill the cabins. This unfortunatley means you probably won't be able to visit certain cruise destinations such as the Norwegain Fjords but you may have little option but to visit the Carribean or the Canary Isles (hardly a hardship in my opinion). If you can't travel at the last minute it may be worth considering taking an upmarket 5 star vessel rather than the mainstream cruise lines. These luxury cruise lines often charge a lower percentage for a single person and so the final cost of the holiday may work out the same as a standard line but you can expect a more higher level of service.
There are quite a number of ships offering singles options "Cruising for Singles
Cruising is great for single travellers. It offers a safe and secure environment in which to meet people and make friends. There are lots of organised activities and social events to keep you busy night and day if you wish. Also there are usually quiet places where you can seek tranquility. Many ships organise singles cocktail parties and will put singles on the same dining tables where requested. I am not sure I got the link right http://www.cruise-network.com/singles.html?gclid=CNjf1fin4JQCFQuJ1Qod43GKSQ
The well known lines are NCL and P & O but there are quite a few more it is a field that is expanding so don't be put off, best visit a travel agent or give 0800 091 1629 a ring a speak to one of their cruise specialists.
Yes it can be prohibitive to travel as a single person. Just to let you know though not only 5 star ships that do good reductions. I am going for 2 weeks on Island Star and very fortunately booked when they had a promotion on halving the single supplement usually paid. Therefore 2 weeks single room supplement added on £200 to my cruise. Now this is for a TWIN cabin (single ones if they have them are usually tiny and on low decks!) on the GOLDEN deck which is Deck 9 and is also a restricted outside. If I had opted for a cheaper inside cabin on a lower deck the single room supplement would have been much lower - so not bad in my opinion and £100 extra per week for the luxury of my own space. Also cruising is the only holiday as a single women, where I feel comfortable. You always meet people at mealtimes unless you choose to sit alone, people and staff, particularly with Island (can be snooty on dearer cruises I have found) often invite you to join them, and there are always places to go to have the "you" time! On land, you can either choose the safety of excursions or be brave and explore with others wanting to see the same things or on your own. It is a SAFE environment for a single person you just have to do your research thoroughly. Google "singles cruises" and you will find an agent called Gills who specialises as others do. I wish you well. If more people enquired over signgle cruises I think the industry would cotton on that they need to be more accomodating over the costs of supplements! I hope you find a great cruise.
I have cruised seven times so far with P&O, as a single occupant. And have paid varying single supplements from 0% to 60%. The tip I would give is to book as soon as the new brochure becomes available, this inevitably means booking 12 to 20 months in advance, depending on when you want to go. Also be prepared to travel in the quiet months, October, November and early December, these are usually the months when the single supplements are at their lowest. The experience I have is that the closer you get to the date of departure the higher the single supplement gets. Unless you are lucky enough to get a last minute deal.
As for the on board experience, if you book with P&O, you can usually select the cabin you wish to stay in.
You will probably find that there are quite a lot of singles on cruises, and doing as much or as little as you want is entirely up to you.
Give it a try, I'm sure you will enjoy it... Bob.
