Can you help me to compare . I am from Bay Area and want to get away for 5-7 days to warmer beach area. In San Diego I have been looking at cottage-type rental in Coronado, Mission Beach and La Jolla. I ran across idea of San Clemente Beach as choice-- can you help me to see the difference. What can I do in San Clemente for that amount of time? Is it true beach has alot of tar? Are beaches better in San Diego? Thank you!
