We will be in Santa Monica (Homewood Suites) from July 1 - 6. Would like some help on what happens in and around SM for 4th of July celebrations? Travelling will be my husband & I (late 40's), two sons 17 & 19 and daughter 14. We've been to Santa Monica once before (5 years ago), but not at this time. We will have a car, but probably won't need it? Thanks!
