Now I'm trying to figure out which of the resorts my sister & I stayed at when we accompanied our aunt & uncle to a trade show at Disney World some 20+ years ago. It was on the monorail & had a main building with an enormous central atrium. (Unfortunately, we didn't get as much opportunity as we had hoped to see the sites & experience the attractions, because both my sister & my aunt were unwell much of the time we were there.) Being able to write off a stay there as a business expense is a definite advantage.
