This is a great point. My parents are amblers - love wandering around, looking at details, taking everything in. I do too, especially somewhere as detailed as Epic will be.
That said, if we only have one day as part of a package or whatever (and depending on lines), we might have to revert to commando-style touring and jumping from ride to ride, land to land, and maybe back again later to walk around more leisurely. I wouldn't book any sit down restaurants or special experiences, and i might not seriously browse shops until the end of the day if there's time.
if park hours are long enough it'll be fine, but I'll have to promise a rest day afterwards lol.
