Go for it! I went on a couple cruises alone and it was great. You meet the nicest, friendliest people on a cruise! Actually, that's how I found The Villages! I met Bonnie on a cruise 4 years ago and she would say what an awesome place it was. Here I am! I even met my partner on a cruise....neither of us were looking for that.
We became friends and continued as friends for a couple years and now here we are.
Actually, if interested we are going on a 3 night cruise in February on RCCL Enchantment if the Seas. When we booked the rates were very cheap. We even have a friend joining us who we also met on a cruise. The solo rate was only a bit over $300. That is with all taxes and port charges. Which is very reasonable I have no idea what the rate is now for FL RES. You are welcome to join us if you would like, so you don't feel alone.
