Who should you tip at a hotel? The bellman gets 50 cents to $ 1 per bag for taking your luggage to your room.  Maids usually don’t expect a tip, but if you stay more than a few days or if your maid does something special for you, a $ 2 tip is a good idea. Room service waiters should get 15% of a bill. Electricity in North America is 110 volts (60 Herz)--not 220.  This means you won’t be able to use your hair dryer or your electric razor unless you can change it to 110 volts.  When telephoning from your hotel room, you will often have to go through the hotel switchboard,  specially for long distance calls.  These calls can be quite expensive, because the hotel usually adds a high service charge to the calls you make.  On the other hand, local calls can generally be made from your room by direct dialing.  You can also ask the hotel receptionist to give you a wake-up call in the morning.  You will always find soap,  towels and linen in hotel rooms in the USA.
