Don't: Get suckered into Ollivanders' interactive wand show
You'll see the famed wand shop, spot a wait-time ticker, and begin shuffling in line with the rest of the wannabe wizards, but stop yourself. Everyone wants to be magically paired with the one wand that's right for them, but the performance is misleading. The tight space can only accommodate one small group at a time -- hence, the lengthy wait -- and within that group, only one person gets fitted for a wand while the others watch jealously. The show is cute and whimsical in a little-kid way but is a total time-suck, so skip the whole thing. Instead, take the shortcut into Ollivanders through its side door, located just behind Wiseacre's Wizarding Equipment, to pick out and purchase your own wand ASAP.
Do: Grab lunch at the Three Broomsticks
The level of detail inside Hogsmeade is completely absurd, and nowhere is its theming more authentic than inside this ancient pub. The food, an array of British homestyle eats, is some of the best you'll find in the park and feels totally true to the dark, damp establishment you're standing in. Wander over to the Hog's Head Pub in the back and order one of the exclusive Harry Potter-inspired beers if you'd like -- considering how much you've accomplished today, you've earned it.
