Yes you could be in space mountain, that probably would be your best plan. You could always hang out in the gift shop for a bit afterwards until it ends. I haven't had an issue with ash the times I've been on, but riding with headphones wouldn't work, you could risk losing them. HEA is 18 minutes long.oh man - didn't even know the ash/smoke could be on you while riding - that doesn't sound fun.
so we have splash from 7 - 8, space from 8 - 9, and 7D from 9 - 10.
if i do want to avoid hearing fireworks, could we be IN space mountain if we check in at 9 for the ride?
You would be in Space Mountain when the fireworks start, but as @SG131 mentioned, the show is 18 minutes long with fireworks throughout. So for the finale, you might be off the ride before the finale if you have a FP. If you took your time though and hung out at the gift shop, you would probably be alright. You then could ride 7DMT anytime after the fireworks were over and be fine.oh man - didn't even know the ash/smoke could be on you while riding - that doesn't sound fun.

As for the crowds, you should be able to go through the main hub as the CM's will make sure to keep the path clear. Just make sure you go through before it starts at 9 or you'll get trapped where you don't want to be lol. It also shouldn't be too bad going behind everything and through Fantasyland, but obviously that's the longer way around. If you did Space at the start, you really wouldn't need to do another ride during those first 20 minutes. People Mover has parts outside, so you would still hear some fireworks if that's a concern. I guess I would do Space at the start and then see how it goes. You might end up off the ride and HEA is already over, enabling you to go to 7DMT. But by all means, ride the others if you want took - thanks everyone! i think avoiding HEA near the 7D area is our best bet. it will be a very crowded night. i wonder if we could do space and people mover or speedway during those first 20 minutes or so. it's battling through the crowds from splash to space that worries me!


Ok - I switched some things around. We have 7D from 7:00 - 8:00 and Space from 8:00 - 9:00 and then another 7D from 9:00 - 10:00 (glitch in the system for my kids - Disney is aware, can't fix, so we did get a bonus FP for them).
I am liking the idea to be INSIDE space for the beginning of fireworks and hang in gift shop until the end. I like this plan even better now b/c my husband is the one who will take my kids on space and i will get to watch the show by myself
We also have a Tony's ADR at 7:40. Is there anyway to fit that into this plan and will there be walking restrictions between these locations?
The Tony's ADR will cause problems. That's just not enough time to work in, and you'll likely completely miss the Space Mountain FP time, even if you are seated right away and eat fast. As @Unvoiced_Apollo said, you'd also likely run into a large crowd waiting for the show, and it will be all standing room only by that point. There is a 15 minute grace period at the end of your FP+, but I wouldn't risk it.Ok - I switched some things around.
