ASMusic looks like a lot of fun!
I really enjoyed your goofy pics with the characters! I always enjoy seeing other adults having fun with the characters, makes me feel less shy with them as well!
We did have fun. Over the last year I really got less and less shy while in Disney. I guess that is a good thing. I never really got a funny look or anything while doing it either. Even when I was alone, if I told the CM party of 1, I would get " awesome" which I guess what they are trained to say if they can't think of anything to say.

I got that more than once.
One thing I meant to ask about your Blizzard Beach update: I realized that you did not go on Teamboat Springs (or what it is called, the family raft ride). The one time I was at BB I did not go on it either, because I was on my own and thought I would need to be a group. Is that true, or would they put you in a raft with other riders? I am not so sure wether I want to sit in a raft with strangers while wearing a bathing suit, but I would love to know wether this is even an option. You appear to be the most knowledgeable person to ask this!
I
did avoid Teamboat Spring because I was alone. Even though, for most of life being in a bathing suit was my uniform of sorts, yes I thought it would be awkward for me to be in a boat with another family I did not know. I would be worried they would be more freaked out by me being intheir raft rather than the other way around.
That being said, I think I did eventually venture down Teamboat springs. However I am not sure if it was during a time where I was alone or not. I may have grabbed ( not literally

) a fellow conventioneer and we headed up there. But I think we got put in a boat with 2 others? I have no pictures so I have no proof. I do remember trying to go on with another person and we got 2 more, I just can't remember when that was. I have been to Blizzard 3 times I think, 2 times for the convention, 1 alone and 1 with my son and the third with family but only my son and maybe husband went to the park that day.
I am not sure if they can send you down alone. With the large raft, you need at least 2 to balance the weight and maybe a minimum of 3 to properly balance it.
My best answer would be:I think they would try for a minimum of 3 or 4 and would combine when needed. I am sure if you got to the front of the line by yourself, they would just pop you in the raft with another family.
