We spent two weeks in June/July at Beach Apartments Hotel, around El Mar Drive and Datura Avenue. $365/week and we had easy access to the pier or the beach, plus our daughters could sleep in, watch TV, ogle the boys of summer -- or dive with us.
Very important -- it answers the question "where is the nearest bathroom?"
We will definitely return.
We were not impressed with the service the day we tried the local Burger King. Mulligans at El Mar and Commercial Blvd. has a $2 breakfast until 2:00 pm, and other very nice entries.
The beach is public and nice for strolling. I walked from Park Avenue to Pine Avenue (the length of El Mar) and felt safe, but it's mostly beach hotels. Ocean Drive (AIA) is busier but has the fire station and park, and I think tennis courts.
We walked along Commercial Blvd. west past the Intercoastal bridge to a used bookstore. Interesting shops but higher prices than if you headed further from the beach.
We also walked to the Publix supermarket and brought back some groceries. Again, prices were steeper than back here at OKC, but convenient for our apartment.
If you need scuba supplies, there is a dive shop off Commercial and Ocean. We used Fill Express on Dixie Highway, and visited several other shops (a jammed BC inflator valve.)
For boat dives, we went a mile north on Ocean to Scubatyme. Reserve by phone or e-mail, they have no storefront.

And enjoy your trip! LBTS is my favorite mainland destination.
