Right in the heart of the parks is Disneyland's Downtown Disney. It is free to go, you can walk around or look at shops, and it's not even 10 minutes from almost all hotels in the area! Starbucks, bowling, amazing restaurants, ice cream, live entertainment and all the Disney merchandise you can imagine is found here.
The FIFTH Anaheim is known for its atmosphere and good drinks. It has a crystal clear view of Disneyland and California Adventure making it a prime spot for viewing fireworks when you're not in the parks. If you are staying at the Anaheim Desert Inn and Suites this is in the building next door. Open from 5pm-12am and closed on SUN and MON.
Garden Walk is a quick 15-20 minute walk or a 5-minute Uber ride from any hotel near Disneyland. It is an entertainment center with shops and restaurants. Everything from an AMC, Boba shop, little eateries, and even an escape room can be found here to enjoy your free time in California!
