2) Yes, continental breakfast is included. Your choice of juice, coffee or tea, banana bread (sooooo good), toast and some pastries. Some people get fruit instead of the bread I think? If you want to order something off the menu, they deduct $5 US from the bill

The superior rooms are the only ones with a covered patio, which are great in case of rain.
