I also love cruising solo, except for the extra costs of course.
I love being able to do what I want when I want and being naturally gregarious I always find people to chat to. Most people are creatures of habit and I find the same people in the same bar every evening, especially The Martini Bar on Celebrity. Eating alone is no fun so I select a set dining time and request being on a large table with other guests. I've only once in the twelve solo cruises I've taken had to ask to be moved to another table and that was because I was put with a group who were on a family reunion. they were very nice but I felt like a spare 'un at a wedding. I only use the Buffet for breakfast so I get my coffee before I sit down then leave it on the table along with my sweater or jacket on the chair while I get my food. If the server/ bus person for my table is nearby I tell them that I'm coming back and not to clear my stuff away. Dealing with luggage can be difficult so I only take a carry on which I can manage by my self except for getting it into the overhead bin on the plane. I'm a 5ft, 75 years old woman so I smile sweetly at the nearest tall gentleman and ask if he would be so kind as to help me. They always do and usually get it back down for me when we land without me having to ask.
