I'm planning my first solo trip for my 40th in July 2025 on the QM2 after about 4 days in London before embarkation. I love traveling, but i tend to prefer to have my own space and explore at my own pace and don't necessarily want to have to compromise with someone else. I'm also a bit of a crazy planner specifically around travel and accommodations. I like watching video reviews and look at so many pictures before and after I make my reservations. I'm not traveling for another 10.5 months and yet I already have a list of the different experiences I want to do (e.g. classes, special meals/teas, etc.) plus a really detailed budget and calendar of events. I think a big part of the fun for me is the planning. It also means that everything is well set so that I can just enjoy my trip (obviously I understand things can and will change, but it's nice to have a foundation). I will gladly take any tips from solo travelers, especially if you've done so on Cunard or QM2!
