The LA Halloween items refresh every 4 hours and may give you free candies. Kim's house has 5 Halloween items you can tap. The best place to recharge your energy without going from location to location is Las Vegas. It has 5 items to tap: 3 outside, the bottle next to the bartender in Chateau Nuit, and the wine bottle in Miraggio Grande. You can throw parties to get candies as well. If you invite a contact and do "small talk," you receive 2 candies. The best place to throw one is Miami, where you can invite 4 contacts. Do "small talk," wait about an hour, and then do "small talk" again. That will get you 16 candies, and getting 5 stars at the party will give you an additional 15. It might vary depending on your Halloween bonus.
