How long are you there? If you are going to be there a while, you may be able to find some part time weekend work with a charter.
If you don't have access to a boat, try kayaking. You are right in the middle of some awesome fishing areas. If you can't find a kayak to use, hit it from the bank. If you have some Zara Spooks with you, give those a try, or go pick up something more suited to saltwater like a topwater from MirrOlure. Soft plastics will also produce from your bass tackle, but they will get torn up pretty quick. You might pick up some saltwater soft plastics and jigheads. Spinnerbaits and buzzbaits are also fun to catch salty fish on.
