Fun! I've been taking DS to
MNSSHP solo since he was 3 (he's now 7). Last year I took DS and DD3 solo. As a parent, those solo trips are really some of the best memories we've had so far, and one of the reasons we sort of fell in love with the place.
Anyway. Being solo with little ones always has some wrinkles, as I'm sure you know! Last year with DD3, we watched the first parade around Town Square. That's not exactly my favorite place to watch, but it tends to fill in last, so we got a spot on the curb 10-15ish minutes before the parade arrived there - which is pretty good in my book (this was at a party around Columbus Day weekend). The dancers/music that come by before the parade helped pass a few minutes (and I got some great pics of them dancing on Main Street).
Have fun!
