I think I know what the tent is at Disneyland in the top photo. I have no idea what this tent was used for at the Disneyland Hotel in the bottom photo.
By the way, I have added 600 pictures to my Disneyland Hotel collection all of which are simply amazing. I would bet the majority have not been seen in as much as 50 years or maybe more. The two above being part of the 600.
