I would hate to be paired with a roomate that was not compatible. I would much prefer a room by myself but don't want to pay double.
I agree with your concern, especially today. I don't like "paying double," but that'a a whole lot better than the risk of rooming with a stranger.
Don't forget, BTW, that you also will "pay double" at a land resort if you occupy a room by yourself because hotels charge per room rather than per person. On a ship, you don't quite pay double because the taxes and port charges are per person even with single occupancy.
If cost is an issue, BTW, book an inside cabin since your cabin does not affect anything else. The cabin is only a place to sleep, shower, change clothes, etc., anyway. Only honeymoon couples (including those on a second or subsequent honeymoons...) really plan to spend much time there anyway.
Meeting people on a cruise line....I guess I just imagine cruises to be a couples type adventure. I have met many couples on my adventures and consider some as friends. But they usually like to do things as a couple and I do not like being a third wheel.
Cruise ships actually draw a fair number of solo travellers because they provide a very safe environment. There's phenomenal security onboard most cruise ships and there's also the option of taking organized tours in the ports of call -- a very safe option especially on a first visit to a foreign port where you don't know either the lay of the land or the local customs. You also have no worry whatsoever about the food, drinking water, etc., aboard a cruise ship because the major cruise lines go to great pains to ensure that they are safe and that there are choices that are reasonably familiar -- and if you decided to try something unfamiliar and find that you don't like it, they are quite willing to bring you something else, no extra charge.
I have also met quite a few single folks who were travelling with friends or relatives, but who were nonetheless quite open to making new friends during the cruise. When a group of singles invites you go join their ranks, you don't become the unwelcome "third wheel" in a relationship.
Thought I would throw this out. See what type of response and advice I receive.
The best adice that I can give is to bo to your favorite bookstore, invest in a guidebook to cruises and cruise lines, read the descriptions of the major lines, and choose a line that seems to suit your personality. Yes, another line may draw a higher proportion of singles, but you're more apt to meet singles with interest similar to your own if you travel on a line that matches your personality and preferred lifestyle. Likewise, pick a cruise destination that you really want to visit because, again, that's where you are most apt to find single travellers with a similar interest.
Now, here are a few tips while you are on a cruise.
>> Aboard a typical cruise ship, you will find more activities and events than at a lot of land resorts. There's absolutely no way to do everything so, again, pick the activities that are of most interest to you because, again, that's where you'll find other passenges with interests similar to your own.
>> When the ship is in port, take an excursion from the ship that piques your interest. Most ports offer a variety of excursions, so there's bound to be something. There's definite safety in a tour group, where passengers tend to watch out for one another and where you'll have a local guide watching out for the whole group. Also, you'll be touring with other folks who chose the same excursion because their interests are similar to yours. Again, it's a great opportunity to meet folks whom you might not meet otherwise.
>> It's very easy to strike up a conversation with a complete stranger on a cruise ship, too. A causal "Are you enjoying the cruise?" with a warm smile to the person in front of or behind you in the buffet line, or seated in the next seat in the showroom, or who happens to look up as you walk through a lounge, is a sure conversation starter. If the answer is brief, follow up with "Now this isn't your first, is it?" An affirming "Oh, no..." opens the door to "How many?" and "Where have you gone on our prior cruises?" -- and the conversaion takes off! A negating "Oh, yes it is!" opens the door to "What are your impressions so far?" -- and, again, the conversation takes off.
Have a great cruise, whatever you decide!
