Prime Time Shuttle OR Supper Shuttle are great. I used Prime Time Shuttle.
I got my luggage, simply walked outside and a wonderful assistant for Prime Time Shuttle guided me to his area (okay, I probably would have gone to Super Shuttle's area, but he wanted my business, ha ha ha). He asked me where I was going....he then utilized his walkie talkie and we sat for 5 or so mintues and the van pulled up. We picked up some other people and then took off to Anaheim. I left my camera !!!! on the van and we called immediately upon entering my room (I took down the bus number and their phone number during the drive) and he returned. I gladly gave him $20. One way ride is $15 per person. I would gladly do this again.
