Just popping in as a former lurker (but I'm also on the USH threads) to give an obligatory hi, I'm here. I'm headed to USO tomorrow and upgraded my ticket to Premier just so I could have incentive to go to HHN in orlando this year on a free ticket. I've been to USH since 2015 but I've never done HHN in USO, and frankly this is only my 2nd trip to orlando period.
Having said that, I've been watching this thread (and the associated USO facebook pages as well) the last few years in hopes I'd get to go some day so I think I have a good idea about the differences between the parks, etc.
To anyone that's been to both parks for this event, throw out your "must" recommendations, since USO is so big with 2 parks. Tips, tricks etc.
Back to speculation.....I have no input. Like, the pandemic fried my brain.
