Sadly, these two phrases are mutually exclusive. The answer to the first phrase is on MS, as close to the hub as possible. But the only way to also meet the second condition is probably to cough up whatever they’re charging these days for the dessert party…
I’m not sure if there’s a spot quite like what you’re wanting. Getting a good view of the projections is much more limiting than fireworks. You really have to be front and center. I prefer the projections, too, and the best spot I have found is the hump at the end of Main Street (not the hub!) I have tried getting closer and farther, to the side. All were bad because I couldn’t see over people. The hump is crowded, yes, but it’s not the worst. You don’t have to camp out to get a spot or anything.
There are times when the projections and the pyro work together, spacially, so being somewhat centered is important, I think. I think the effect would be less if viewed from areas extremely off to one side or the other. I’m trying to avoid spoilers, but just wanted to say there were some really neat things that happen. We watched from Plaza Garden Dessert Party area, and it was great!
Can I slightly hijack this thread to ask how Once Upon a Time fits in with HEA? It’s showing up in my plan as 45 minutes after HEA. I thought that HEA was the fireworks and OuaT was the projections. But don’t the projections happen first? I am of the opposite view of @mousematt and only really need the fireworks!
