We went alittle over a week ago and could not get same day FPs for TSM.Toy Story Mania is easy to get as a same day fastpass. I would fastpass SDD and then look for a TSM after you use your 3.
SDD feels a lot longer than &DMT to me - Its such a fun ride. I would totally get the FP for it and rope drop TSMSDD is 2 minutes, SDMT is 3 minutes, BTMRR is 7 minutes.
It's longer and better than Barnstormer.We have a 14 and 17 year old and trying to decide if it's "worth it" to get a FP for Slinky Dog rather than a Toy Story. Kids love Toy Story ride. DD likes Mine Train, but DS doesn't and neither would do Barnstormer unless there was no line and sort of like a joke. Any thoughts? Not worried that we'd "miss" it bc it's new--we are more into slower rides if they're themed well (why they like Toy Story). Thanks!
