You can usually get a pretty decent rate here. They offer 'FREE' pickup at the Airport, and have a nice pool, and FREE cocktail hour(s) at night, and a FREE breakfast in the morning. Breakfast is Bagels, Rolls, Cereals, muffins, and juices/milk/coffee.
While at the hotel, you can get a private company to take your family directly to your resort of choice for a lot less than Mears. And, assuming that no one bites the driver, he will likely offer to pick you up after the vacation and take you back to the airport.
Last year, my family (4 Adults) paid $30 for a trip from the Airport to Port Orleans, then $40 from Port Orleans to the Airport. (I believe). Anyway, it's far cheaper than renting a car, or paying $20/person to Mears.
