Not sure where to put this. Seeking some advice on how to proceed with the following incident that occurred last night at a Bangkok hotel (full service hotel part of a worldwide chain).

I had two rooms booked for 2 nights, one for myself and the other for my colleague who was to be arriving at the hotel later in the evening. She's a local in this country but is based in Singapore like myself. I put her name on the reservation for her room, and told reception upon my own check-in that my colleague would be checking into the other room later in the evening and to prepare her room accordingly.

Around 11:30pm I am awoken (early meetings this morning) by the phone in my room, as the front desk is calling to ask if it's okay to let Miss [name of colleague] up to my room. I ask the front desk agent what he means, and he repeats the question. I tell him my colleague has a separate room booked ("2 separate rooms!"), upon which he asks me to hold the line, following by an apology. My colleague was quite offended by this given that the implication was that some guests 'bring prostitutes up to their rooms'. I also find it quite offensive and frankly downright unprofessional. I'm sure it is not uncommon for guests to bring prostitutes to their rooms here (even though it is a full service hotel), but that this would even enter the mind of the front desk agent is not OK.

I haven't spoken to the hotel about this, but overall I've had an amazing stay so I really have nothing to complain about except said incident. It was definitely a bit awkward though, between being woken up while sleeping and being asked if it's OK to let a girl (my colleague) up to me room.

Should I just let it go? Complain? Seek compensation?
