Went in December as a party of 3, and had a man who was solo that they sat at our table as well. Doesn't matter the price, they tell you ahead you will most likely be grouped if the show is sold out. He turned out to be a nice man and we had a nice chat before the show. In theory, I'd love to have a table to ourselves if we are less than 4, but it honestly wasn't that bad.
I would never assume to have a table to yourself if you are just 1 though!! I'm surprised it's happened as many times as it has according to above, but I guess it depends on time of year!
