'Tis the season to get boozy. Grab your (21 and older) friends for Rockin' Around the Rooftops — a seasonal stroll through six of Austin's premier holiday-themed pop-ups.

Ask for a passport at any of the participating bars and get it stamped as you stroll. If you get all participating locations stamped before Wednesday, Dec. 25, you'll earn a $50 promo card prize for future use.

Turn off your resting Grinch face. Here's what's in store:

Nightmare Before Moxy | Tim Burton’s "The Nightmare Before Christmas" comes to life at this pop-up, which features festive drinks and an atmosphere that will make you forget all about Halloween.

Naughty or Nice at Upstairs at Caroline | Enjoy the twinkling lights of this rooftop bar and the Austin skyline with rotating specials — nice guests get Rumple Minze while naughty guests get Malört.

Snow Much Fun at Edge Rooftop | Snow falls every hour on the hour at this festive bar, where you can enjoy s'mores boards, fire pit rentals, and snow globe cabanas.

Winter-Sol at Otopia Rooftop | Get cozy by renting an igloo — complete with themed cocktails, a vinyl record player, a cookie decorating kit, and board games — for yourself and five of your favorite elves.

Yule at Azul | Bundle up in a themed cabana where you and yours can indulge in a tableside s'mores kit, postcards to send, fresh blanket service, bubbles to go around, and photo ops galore.

Holiday Hideaway at Zanzibar | Enjoy a tropical holiday on this rooftop, where Santa slips into his swimsuit, spiced cocktails have an island flair, and the flamingos wear Santa hats.
