I can't believe I'm going to say this... but I think Epic Universe needs more retail? I know space is limited, but more retail opportunities within Celestial Park would be great. Not asking for more generic Universal merch, but more unique stuff like the Crystal Arts shop at MK, a Halloween shop, wood carving station at HTTYD, etc.
I'm sure over time they'll add stuff, but Epic Universe was the first time I visited a park and didn't feel bombarded with merchandise opportunities lol
