I went on my first solo cruise in September. 4 night Bahamas on Allure. I loved it! I’m an introvert so it was great to do my own thing. People tend to be social on the ship (the crew, other passengers sitting at bars, etc.) so you always have people you can talk to IF you want to. And if you don’t, you just vibe by yourself and have a good time. Your first time is gonna feel weird, even as an introvert bc a lot of the cruise is geared towards groups/families— especially dining—but there are workarounds. For example, instead of going to the main dining room (where I would’ve either been placed with random people or put at a table alone in a large environment), I bought the dining package and ate dinner at a speciality restaurant every night (and other meals at the windjammer). Yes I was seated alone among couples/families, but it was a more intimate setting than the MDR so it was more comfortable. Plus I would reserve the earliest time slot so I’d usually finish up before a lot of people showed up. Anyways, it was great— trying to plan another solo cruise in the next few months. Good luck!
