Phew, OK... got back.
Here's the review.
The ride itself is pretty painless.
HOWEVER, make note of the pick up times at your locations.
Steps:
1. Go off the plane, get your luggage.
2. Step out to the shuttle waiting area under the GREEN sign (it doesn't say
disneyland, but that's the right sign trust me).
3. Wait for the big bus with Disneyland express picture on the outside.
4. The bus will take you to Disneyland Hotel where the ticket attendant will get on the bus and take you money for the trip (one way or roundtrip).
5. Then the driver will take you to your hotel.
6. The return trip works the same way.
Now, the bad things:
1. The bus only picks you up at certain times (on the hour, 9pm, 10pm, etc). I arrived the shuttle area at 9:20pm, so I had to wait 40mins for the bus. Make sure to call the gray line and confirm pick up times at your terminal before you get upset for waiting too long.
2. The bus stops at ALL the different terminals at the airport and drop however many people on your bus at their hotels, so the travel time might be awhile since it's a pretty big bus.
3. I stayed at Anabella and the return bus also comes every hour but on the halfs (7:30pm, 8:30pm, etc.). Depending on your return flight time, you might have to hang out at the airport for awhile.
The good stuff:
1. $5 discount voucher for rt on the website. Helps with the budget.
2. Depending on your hotel, no need to arrange a pick up to the airport since they come on a schedule. Contact your bell service to confirm.
Anyways, I wouldn't mind using this service if I arrive and depart in during off times. But if during busy times I would probably try a different shuttle service with smaller vehicle.
Feel free to ask questions.
Be glad to help.
