My husband and i will be flying into San Diego and staying 4 days before going on to Indian wells for 3 more days. I came across a hotel that appeals to us mainly because they have a great tennis there, it's called Rancho Valencia. It is about 18 miles to downtown San Diego, we've never been to San Diego so not sure how traffic would be going back and forth from hotel. Not sure if i should forget about going to Rancho as it may be too much of a pain going back and forth. I would appreciate any advice from experience travelers or locals who know the area.
