Spice Road ADR for Epcot Forever

Unfortunately my only Epcot evening will be on a Saturday night during F&W but also the first Saturday showing of Epcot Forever at 10pm. We are rope dropping DHS for a 6am EMH opening so needless to say I will be tired & want to sit.
I am currently planning an ADR at Spice Road & of course over thinking everything. I plan to ask for a table by the water and will let the server know we will be staying for the show, probably ordering extra drinks and will definitely be tipping well for that.
I originally had an 8:10, then thought that might be too early so I changed it to 8:30 & now I think that might be too late. My DD thinks I’m nuts booking 2 hours in advance. What do the experts think?
