so me (im 15 btw) and my friends family are going to LA for 3 weeks in summer, and we are staying at her Aunts house. I am planing on going to the beach with her a lot, probably go to Disneyland, shopping etc... so i was just wondering, what should i all bring on vacation with me? any things NOT to bring on a plane, how much money etc. any info would be greatly appreciated
