ILG does need to be renovated. Lot A and B often fill and Lot C is not a good alternative. I don't know if I would tear down the Quality Inn but there is some room for expansion. There is a small field on the North side of Lot A that could hold roughly 200-300 spaces. They could maybe lease some of the parking from the Quality Inn. Lot C could work if there was better signage and a shuttle service to the terminal. On their website(something TTN lacks), there is a public notice about the DRBA recently conducting a study about Terminal Improvements. If this plan moves forward, it will probably be in Fall 2014 like with TTN.
rtalk25: Shuttle Service is 9am-7pm, If Frontier is delayed till late at night, then they can call Delaware Express. Budget/Avis will stay open later I believe, especially since Frontier is bringing in so many customers for them.
