No- there was a fee for a ‘guest’ .
Technically the hotel would say you need to pay for bringing a guest.
But if you make your initial booking for 2 people, same price anyway, and then decide to bring a guest to the hotel during your stay it is ok, as long as it's the same guest and not different guests.
The hotel will ask for identification from your guest on arrival
