If this was a real business instead of a magical internet business you could take the 3 pages of chores and tell them where to stick it. Why are they allowed to alter the deal once you arrive?
Its not really a magical internet thing in this case, this reads like what a landlord would do with your security deposit. What do you know, let slumlords become unregulated hoteliers and they will do shady slumlord crap in the hotel industry too.
