It's Disneyland! Like you even need an excuse to go!
Less expensive than Disneyland with a distinctly more Californian theme (Old West/Gold Rush/Beach vibes/etc.)
Probably the closest pier to the venue, but there are many other/better beaches along the coast.
This is our favorite spot in Downtown Fullerton but there are many other options for bars and nightlife within walking distance.
A nice big mall that's a few miles away from the venue in case you need to do any last minute shopping.
