You should be able to move it earlier if you check all the time....especially the day before or even day of....but I wouldn't risk it, as if you had a 90 min experience, but you had to wait for 20-30 min ( as you are in the throes of peak dinner time) you would most likely be late for your AH, which doesn't seem cost efficient....I would also go for something like Boma, which is closer....but I would also think about the snacks you're going to have there, they might not be as fun on a full stomach....
