Be friendly to the hotel staff, and they will be nice in return
The hotel employees will always be at your disposal, so do not be afraid to go to them if something goes wrong with your stay. Remember that it is their job to make sure your stay is pleasant; they are in charge of making vacations unique.
Whether it’s an extra pillow or if, after an embarrassing accident, they need to unclog the toilet, nothing can’t be resolved in a polite conversation with the administration. Be communicative, and above all, be kind; be the guest that everyone would like to receive in their homes.
