Thanks to everyone for all your information. I was wondering if anyone who has experience with using the Disneyland Resort Express from Southern California Gray Line could help me. I understand they don't take reservations for going from the airport to the hotel, but how do you co-ordinate with them for a pick-up from the hotel to the airport? Is this done before the trip, after arrival, from the hotel? Any experience tips would be helpful as well. We are staying at the Sheraton Park Hotel.
