Having fun reading along so far! I went solo for the first time in May and it was great. I will say, I was disappointed to not do more TS meals (I did Tiffins ROL pkg and Boma breakfast, plus a last minute BOG lunch). I had planned to just do QS and the Flower and Garden booths, and that got old fast. And once at F&G, I didn't end up eating very many things at all. The good thing about being solo is being able to find last minute dining and....last minute fast passes!! I had so much luck with passes on my own. Just refresh, refresh, refresh when looking for day of FPs, you might have great luck too!!
MVMCP on your own will be great, especially if you have characters you want to meet. We went as a family last December, and loved it, but didn't get to do a lot of character meets during the party(or any really, outside of a fun moment with the country bears) because I felt guilty about "wasting time", and everyone else wanted to do other things. The best part of a solo trip is not worrying about what anyone else wants to do!!
Looking forward to following along and hearing about your plans!!
