I'm at the Marriott across the street for the duration. The Hilton's Saturday night was already sold out by the time I booked. I've stayed at both many times over the years for the annual NAMM show and now more recently for WonderCon. They're extremely convenient to the convention center for anyone else staying there, but there are plenty of other hotels close by. Plus with Disneyland right there, it's just going to be an amazing time for anyone coming to town!
