Some of the hotels in Florida that are close to the beach and theme parks include: Walt Disney World Dolphin, Wyndham Bonnet Creek Resort and the Disney's Beach Club Resort. These hotels are near the theme park known as Disneyland with beautiful marine world. They provide transport to anywhere you would wish to go. You can choose others on http://www.choicehotels.com/en/travel-ideas/theme_parks.
Most hotels in the greater Orlando area -- especially in Kissimmee -- have shuttles to the DisneyWorld parks, Universal, Sea World, Wet-n-Wild.... They do NOT shuttle to the ocean beaches. You'll need a rental car for that. Cocoa Beach is the closest; about a 45 min drive from the MCO airport. *** hotels close to the beach won't have shuttle service to the theme parks.
