We have stayed at Playa Bonita many times in a 40 foot class A. If you are beach front, and park so that your front window is facing the water, you should be able to reach the electrical connection with the 25 feet of cord that I'm assuming you have. However, sewer maybe a different situation depending on the site. For half the beach front sites the sewer connection is on the other side. That means you would need at least 40 to 45 feet of sewer hose. If you don't want the view out your front window then it should be no problem. The in line spaces should be no problem as the hook ups are at the back. The electrical there is 30 AMP, but they will wire in a 50 amp for you for a few dollars.
