Oh, my, I can remember our first trip to FW! We needed room for 5 or 6 (sister's husband bailed at the last minute as we thought he would so really room for 5) and we picked FW. I was so nervous when we planned and when were driving up--I so wanted our first trip on-site to be great! It was!!!!! The cabins (homes back then) are super and the atmosphere is pure Disney!!
Enjoy the anticipation!!!
Suggestions--take a ball for the kiddies. Our's loved being told to go out and play in the street! Take a couple of flashlights, stuff for smores, and rent a golf cart for even just a day if you can. That way you can really enjoy all FW has to offer!!
Yes, you can see the castle from the beach at FW--probably farther down from the marina, though. I have a wonderful photo taken from the far end of the beach at sunset that shows the castle and Space Mountain!
