@Schweino : I confirmed that you may dine early and return for fireworks viewing on the patio by showing your receipt.
@dreday3 : As of now, you can buy a drink at the bar and take it out on the patio without having a dinner reservation - except at prime times during the busiest days of the year.
There is a lounge area outside with a bar and couches, tables and chairs but no one is manning the outside bar due to labor shortages.
I recommend dinner at Topolino’s. The food is great, although my husband hates the breadStyx.
