welcome to ft!

imo this seems like a case of misunderstanding - maybe front desk told housekeeping that you left already or smth similar.. people who steal from you (not "rob" as it has a very different definition) do not come back and return passports etc..

people will come into your room without permission if you stay in hotels - the sooner you explain it to your kids - the better... i'd add that people often leave tips to housekeeping when they depart and perhaps that caused misunderstanding..

it was clearly mismanaged by hotel with a nonexistent follow up that reflects poorly on hotel and marriott and deserves some sort of response however "i was robbed" is an incorrect way to describe what happened.... if you have a specific ask from hotel's gm eg comp a night or whole stay or smth similar - do that in a follow up email
