Yeah - tis one thing that always frustrated me with Universal. Hopefully
Epic will be different.
To be fair the late nights at Disney are not what they used to be - I can recall staying to 1AM many times - that is a lot less rare now.
Still Universal has always been ridiculously early IMO - other than HHN.
That said if your a late night person and don't have an AP it might be worth watching for the Orlando Informer weekends.
Its a little more expensive than a two day tickets - but you get it till 12:30 or 1:30 AM depending on the night.
It also includes food and snacks throughout both parks and a walkway between t he parks.
Its a lot less crowded and you can get in at 5PM - park closes at 7PM or 8PM for the general public.
Very short waits and overall its well worth it IMO - as long as you don't already have an AP or tickets.
