(First, I don't understand how anyone can be "jealous" of something he doesn't have. I think some people are mistaking jealousy for envy)
Personally, when I am on holiday, I don't wish to spend most of my time in a hotel room, so I'd go for a nice, but not elaborate room. However, when traveling for an overseas trip, I would like business class (I doubt many know what first class is; it's extremely elaborate and more than most people want or need).
Where I'd want the most money is for transportation within the city or countries and for restaurants!
