one of the best experiences during our vacation was staying @ hojos and using grayline buses to get around. we bought a 4 day pass that i purchased online and printed out. i made a ressie with them for our days and they picked us up right from the hotel and went around the corner to their bus depot. i gave them my print out voucher and they handed me a piece of paper that had 4 day pass on it and they would circle the days i would use it and that's all i needed. on the way to our destinations, (san diego zoo, seaworld, universal studios/hollywood tour), our bus drivers would tell us about the area. very entertaining and very informative. on the way back from your full days at the parks, you could take a nap. it was only $129 ea. for this 4 day pass!!! way cheaper than filling your tanks up, getting lost on that 6 lane freeway, not having to pay for parking, and being able to see bette midler's house on the cliff. i would highly recommend this for those of you who fly in.
