Yeah I was "a lot better" this boat trip, probably because of all the precautions . Only went as far as stage 3 on the seasickness scale.
stage 3- nauscious, hung onto the rail, but not so sick I wanted to die.

Marina area - LA
Marina Del Rey is a nice area, you can walk or bike to Venice Beach, a place not to be missed
I know the Holiday Inn Express Marina Del Rey is there, but haven't been inside; might want to read the reviews on-line. Just make sure to note the parking fees, lots of hotels at the Marina charge.
