I traveled solo in April. I booked the pub crawl for 2 as another solo was supposed to join me but canceled the night before, or maybe the morning of, so I went a head by myself. I didn't really notice anyone else solo, but it was fine. May have been more fun with a buddy, but the first time I went with someone who was a stick in the mud - it was more fun going by myself, than with him! I'm booked to go solo again in November. It wasn't only couples, there were dad/son, friends, etc. I'm on the shy side, but there'll likely be friendly people who include you/welcome you at the tables/bars and the sing-a-long on the bus doesn't require a buddy! Lenbert is good about watching out for you.
