Single on a huge cruise ship!!

It was somewhat against my will that I landed on the Carnival Freedom. This came about because the cruise was advertised by the Historical Museum of Southern Florida for its members and it wasn't mentioned which cruise ship we would be on. Having been on a cruise only once before, in the South Pacific on a ship which carried only 250 passengers, I was totally overwhelmed when the Freedom loomed. I was also put together with another lady, the museum travel agent had assured me was very nice, my age etc, but in the end was totally unbearable. The service desk was extremely helpful in finding me a single cabin after two nights at an additional cost of $150 which was acceptable. There also is no shortage of food on this ship, but one look at the extremely obese majority of the other passengers could put you off food for life! It wasn't nice either to see them in the pool or on the deck, but that's not the cruise line's fault. Arrival time at the first port of call, San Juan in Puerto Rico was very bad. The ship docked at 6pm, when it was getting dark and left again at midnight, so there were only a few hours on the island---in the pitch black dark. I failed to understand what could be funny about a hairy chest competition but they make a lot of effort to keep people entertained. For a single woman here is the best advice: find a quiet corner to sunbath or read, make sure you have a cabin with daylight and otherwise make the most of going ashore, preferably on your own so you don't have to wait until whatever group is together and you are not herded to places you don't really want to go.
