I go back and forth to Los Angeles (assume that is what you mean rather than Lower Alabama, or Lousiania)--which are both refered to L.A. around here in Pensacola.
We have found that there is only a couple of miles difference between going thru Houston on I 10 and Dallas on I 20. Our motor home does not like the Lousianina I 10 freeway, with the causeway bumps--and Houston Traffic is terriable (we try and hit it Saturday or Sunday).
There are a number of diving sites in the Gulf off of Pensacola and Destin. In April, we are still subject to Northers--and it can get rough offshore--even 20 miles or less. Also in April the water is still farily cool; it will be high 60's to 70 the first week of April. (Similar to summer conditions in S. Calif. I should be home the first or second week of April, if not Marie will be here, so give us a call.
I recommend Pensacola Shipyard Marine Complex. It is $5 in and out to launch. The security is good there, and I suggest it over any public ramp (actually the ramp was paid for by the country) and adminstrated by the shipyard.
The aircraft carrier Oriskany is the most famous dive site we have--it is 67 feet to the top of the Island. The deck is more of a techinal dive at 120 to 130 feet. There are many other dive sites locally, some inside the pass and some right at the pass.
Cruising this time of the year is excellent. The temps can vary, and there can be thunderstorms, but the average low is in the high 50's and the average high is in the mid to upper 70's.

We will be happy to fill you in on specifics of places to go and things to do when you arrive in this area. I am sure that Marc will tout the virtues of "old Flordia" in Apalachicola--and we love it down there. I like to think that the diving is better up here, but both have virtues. Most of our diving is on artificial reefs.
