Yup.
My last cruise was sold out and they couldn't accommodate a private table for me, but it ended up being ok. A mother and adult daughter (honestly I was probably closer to the mother's age), a set of BFFs, and me. The BFFs kind of kept to themselves, but the mother, daughter and I talked and it ended up fine. Our server called us her Spice Girls.
I was on another one solo and it was like they did a solo dump - myself and two guys, all traveling alone. The guys hit it off and obviously had a lot in common in all aspects. I read my nook the first night, had Palo the second night, and the third night I thought I'd try Cabanas - but it was like they'd taken all my least favorite options to put on the menu, so I went to the dining room during first seating to see if there was a chance I could be moved. They were able to move me - my servers only had one very large table, so adding one solo diner was nothing. It was a MUCH better situation. I had the same head server, and I asked him to please let the other team know that it was NOT them and he said "Oh, we all were shocked you made it through the first night! We know."
My Wish cruise is now sold out, so unless it IS private tables, I'll be stuck with people again. I'll have the nook all set just in case. Then I can be the one people on here talk about being "the weird girl who read the whole time".
