Ok, based on my experience tonight, definitely get HM if you know you want it. I spent a ridiculous amount of time with two of us looking to try to get HM with a window starting between 6:30 and 7:30. Like we started looking at 5 and could not get anything to pop in that time frame (we were trying to work around an ADR and trying to make it an early evening). We finally changed plans to stay later to use an 8:00 that finally popped but we easily spent over half an hour with two of us looking for a party of two (in lines, while walking, while waiting for dinner). Had trouble with Splash early afternoon too. Bah humbug, FP availability.
