I love them. I would reply more on why but hate typing on my phone. But I’ve been on six of them between 7 and 14 days. They give you the ability to get a taste of different areas and the entertainment on the ship is usually good. I’ve never felt “trapped” on a ship as they are very big. I have another cruise booked later this year and looking forward to it. I’m an introvert too. I know some people like the interaction with other people but that really isn’t my thing but I do like cruising.
I had an incident where my driver’s license was missing the last letter of my middle name and the plane ticket had my full middle name, the TSA agent questioned it but didn’t hold me up.
When I renewed my license the next time I made sure they were able to get my full middle name on there. Just didn’t want to get the wrong agent.
