My 6 friends and I from Ireland are planning a road trip of California/Nevada/Arizona from July 24th- 17th August 2013. We hope to hit San Diego for 3 nights around the 5th August. I'm looking for help to plan our itinerary around the San Diego area. We plan to go to Sea World and the San Diego Zoo. Are there any other sights that people would recommend? Also what places are good to head out in for a lively night. Would it be feasible and worthwhile heading to Tijuana for a day? We are also looking for cheap but decent hotels in good areas, say maybe around $60 per person per night. Could you guys recommend some places that are good value or a gem of a hotel that has low prices :-) (asking a lot I Know!!!) We'd really appreciate your feedback on this.
