Anyone dealt with Resort Closings?

I am looking to buy a beachfront timeshare in southern California (near where I live.) I want something on the sand where my family and I can hang out and relax.

I know some of the timeshares are listed as beachfront, but when I mapquest the address, there is a street that has to be crossed.

Anything to watch out for in buying resale? We have never had a timeshare before. Thanks in advance
