Goodness, absolutely! I went on (most of) Fall tour '18 with Phish - from Hampton to Vegas - alone with the pup! Went up to MN alone recently to catch a few of Neil's shows in -418F weather (about 900 miles one way). One-off shows are also viable on solo status, which yields a freedom of association and movement untied to the wants/needs/neuroses of another. I tend to meet more people alone - heck, I filled an address book on the tour; but, that said, there are times when a party group can't be beat, especially when a hotel stay is warranted.
