Hotels near theme parks do more than offer a convenient respite from the lines and crowds. Largely aimed at families, the most elaborate of them operate as park extensions, with immersive design and enough amenities to ensure that you can retire to your room after a busy day and won’t have to leave it again until morning. The following new and improved resorts champion proximity and entertainment, and many come with perks such as free shuttles to the theme park, on-site ticket sales, early park admission and line-jumping status.

Less than 2 miles south of Disneyland, the new Great Wolf Lodge Southern California offers a sprawling 105,000-square-foot indoor water park to retreat to after a day with Mickey and friends.

In addition to standard rooms, the resort offers themed suites with cabin décor and bunk beds. Dining choices range from wood-fired steaks to poolside hot dogs.
