Take a lanyard with a holder for your admission cards. If you are used to magic bands in WDW, it's a little odd to realize you have to take out the card. lol
We did this trip last February and there was a cold front. VERY chilly, so make sure you do bring things for layering. Make plans for your free time in Hollywood - the area next to the hotel isn't the greatest. We went to The Grove for brunch and SUR and Villa Blanca (Yes, BRAVO fans..lol) for dinner.
