By all means, do the Boobs Cruise. You'll love it, but there is just one thing.. Since you are a single guy expect to get a good natured ribbing by the crew. It's all in good fun but you might end up getting your ass paddled. It's part of the fun and you can take it. Other than that, go and have an awesome time. We've met plenty of great Canadian people there, some couples, and some single dudes, but great people each and every one. Enjoy your adventure!
