Can someone explain me what is the purpose of:
- Plant Room,
- GSM Room and
- MCC Room
found in certain hotels (at least in one)?
I have just found them while staying at Premier Inn next to airport in Abu Dhabi, United Arab Emirates.
Both rooms are located at the topmost floor (where, in case of this hotel, there are no guest rooms, just the pool and the gym), both all closed all the time and both have "Keep Closed" label on doors.
MCC Room and GSM Room seems to be of size of a typical guest room (or two) while Plant Room seems to have the size of 1/3rd of entire floor, taking area of whole corridor and fifteen guest rooms.
I've visited a number of hotels previously, in many countries, including other hotels in UAE, but found these three rooms only in this Premier Inn hotel.
