UPDATE FROM OP:
Ok, we are back. And we were able to ride both rides. Yes, they are different.....but not in a way that I was expecting. When my husband asked me about TSM, I had to tell him it was basically the same as the Buzz Lightyear ride, where you sit and shoot at stuff. He was "ok" with that. (he does not like fast or thrill rides, and being as I have tricked him into getting on some faster rides in the past, he does not trust me entirely when I give him the low down on the rides. (insert evil laugh here......)
That being said, I found both rides enjoyable, although we got to HS too late late in the day to get a FP, and waited an hour to ride it, so that factor may influence my judgement on these rides, but I think I enjoyed the BL ride a bit more than TSM.
Thank you everyone for convincing me to ride both, to see for myself the actual differences in the rides. The DGS(5) loved them both, and seeing him enjoy himself was worth any wait. I will say the TSM queue was more entertaining for the DGS, but that being said, an hour was almost too long to wait for this ride.
Since this was his first trip, and we are now more familiar with the lay of the land, we will definitely plan our days to arrive earlier on our next visit.
We took a very laid back approach to the parks, just doing a few must do's, and avoiding the need to do "everything". It was actually pretty relaxing, and with a 5 year old, we still felt like we did enough.
Thank you again to everyone who responded!
