For the poster above,
gboiler1 who asked about DL Express and Super Shuttle -
I have used the Disney Express twice on my two most recent visits.
Both times i have had positives ( price, comfy ride ) and negatives ( late pick up due to not getting my reservation through the hotel or driver).
Getting TO the DL Resort is easy FROM the airport of choice.
You simply hop on curb side at LAX and the bus heads off to the DL Hotel. Here fares will be collected and then you will continue on to your hotel.
At SNA you walk outside curbside and purchase your ticket to ride at the small white booth for the DL Express.
As of May, the rates were about $35 round trip to either airport.
SNA is a quick 30 minute ride and LAX is about 45 to 50 minutes. ( with no traffic issues ).
You will stop at multiple hotels before reaching yours, unless of course you are staying at the DL Hotel.
The Disney owned hotels and a few non-Disney hotels will drop you off right at the hotel lobby...but be forewarned that this is usually not the case for most non-Disney hotels.
You will be dropped off at the closest 'bus stop' along the DL Express route...which can be near your hotel, or several minutes walk away.
Something to keep in mind if you are loaded down with kids and luggage.
Getting BACK to your airport is another matter...especially if you are not staying at a Disney owned hotel.
Non-Disney hotel pick ups are usually not directly from your hotel as noted above, but instead at one of the local public transportation bus stops.
Some of the better non-Disney hotels, or 'Good Neighbor' hotels do pick up right at the lobby...but many others are at bus stops located around the Resort Area.
So you may have a short trek ahead of you the day you depart.
Also, you MUST reserve your pick up time a full day in advance. DO NOT rely on your hotel, or drivers who claim to make the reservation for the return pick up for you. There is about a 95% chance it will be forgotten and you will be sitting around waiting to be picked up.
My two experiences i learned the hard way....and finally took the initiative to just book my own reservation the day before.
The buses however are nice...your typical long haul comfy seated motor coach.
It is a nice ride ...either airport ( i have done both ).
The drivers were friendly and were eager to chat, but that might have been because of the hour i arrived and the fact i had the bus all to myself!
At $35 for round trip, the price is appealing to the budget traveler who does not want to spend a lot of money on taxi rides ( especially from LAX! )
Super Shuttle i have not used to date so i cannot really comment.
I have been told that it is also not a door-to-door service and that you will make many stops before reaching your destination in some cases.
Hope this helps you out !
