Hi there, Betzaida!
Welcome to planDisney and thanks for submitting your question to us. I'm so happy to hear that you're planning on attending
Disneyland After Dark: Sweethearts' Nite! It's such a wonderful event that celebrates all things romantic and Disney!
I'm happy to report that, at the time of this writing, no taxes are added to Disneyland Resort
Theme Park Tickets, whether they are for general Park admission or After Dark events. The quoted price that you see for your ticket will be the price that you pay at Checkout. There will be sales tax added to any food or merchandise purchases that you make during your visit, however, so budget for that if you need.
I love the unique characters you get to meet at these After Dark Events. If he's around for next year's Sweethearts' Nite, you'll have to say hi to Big Al for me! And how cool to be able to see Indy and Marion together in Adventureland?
Betzaida, I hope this information was useful and I wish you the most magical visit to the Disneyland Resort! Please write back to us again if you have any more questions. We'd love to hear from you and continue being involved in your planning! Until next time!
Wishing You a Great, Big, Beautiful Tomorrow!
-Al
