The vast majority of times there are no issues or awkwardness on solo trips - they're awesome all the way around. And I highly recommend them. I say that as the preface to the fact that on rare occasion something strange can happen (although whether or not it's uncomfortable depends on whether you let it make you feel that way).
I've only had one incident that I noticed. During a solo trip last month, I had a PPO breakfast at BoG. I didn't have one - but four separate reactions on that meal. Odd but it happened. The first at security check-in ("Wait - did you say it was only you?" *brief hesitation and the "sad look"*). The second at the BoG check-in booth (CM started laughing when I said it was just me). The third was the CM taking my order ("Who else in your party". "Just me". "Okkkkaaaayyyyyy"). The fourth was a guest - a snide comment about one guest taking up a table at a busy restaurant. I couldn't care less, but I did notice. I don't point this out to put anyone off BoG or solo meals or trips - just that it can happen (and it stands out just because it was so odd in my experience). I don't think I'd do BoG breakfast again - not because of what happened (I kinda like being a contrarian) - but really because BoG breakfast is sort of overpriced and terrible for what it is. Happy travels everyone!
