So if this were me (and it wouldn't ever be because I would never rent a place without a pool in the first place), I think I would have forgone the Disney trip if a pool meant so much to me. It sounds like you are not going to have a very nice time if you don't have a pool. I was down in July. Yes, we did have a pool but I think I only got in it twice. The kids of course were in it everyday. I myself was in the Gulf most of the time. I had to dodge the jellies, and the June Grass made me look like the Swamp Monster but it was worth it to me. I also put my beach chair at the shore and enjoyed the waves washing over my feet and legs. It was pure heaven to me. Sometimes you have to make lemonaide out of lemons and think of this as a lesson learned. I will tell you this as well, there are many condo complexes that have pools and if you get a condo pool side and not Gulf Front, then the cost goes down a lot. Just a thought if the pool is more important than a Gulf View for you. Now it doesn't sound like a pool is going to appear for you, so if you are staying in Grayton enjoy the lake and the Gulf, because IMHO, it doesn't get any better than that!
