I'm going on my first cruise, to Alaska, and doing it solo. The dog sledding (plus helicopter ride) looks amazing and is the only excursion I am thinking of. But I will be alone. I'm sure they form groups of people for the sledding itself, which is fine by me, but will it be uncomfortable? That is, will people be like, "wow, it would have been cool but there was some random old dude on our sled with us". Has anyone done this alone, or have any thoughts on it? Thanks.
