Hermosa Beach is a fine place to spend Thanksgiving Holiday, and Manhattan Beach just next door to the north, too. The cities are two miles pier to pier, so you wan walk everywhere. The beaches are pristine. There is a bike path that runs along the ocean, and several places to rent bikes. The "Strand", boardwalk is right out the door along the beach cities. Do you have an address for the Hermosa condo?
I have friends who return "home" to vacation from other parts of the country and stay in vrbo.com, vacation rentals by owners in Manhattan Beach in the summer.
One is this two bedroom Apt. on the beach that sleeps 4-6:
This one also sleeps 4-6:
They are strict on the amount of people sleeping there, a few extra to visit on Thanksgiving is one thing, but not to "smuggle" others in overnight.
Lots of shops and restaurants in both cities. Here is a video to give a lay of the land:
Check for other listings on vrbo if you more than 2 bedrooms.
