We are a party of two also my plan is to check in early which can be done according to the confirmation email as early as 4 pm
I then plan on returning 8:30-8:45 as it states you should arrive up to 90 mins before the start of the fireworks (10:15)
I figure by this time we will be ready to grab treats and just relax a bit
As of now the plan is to catch the second parade
