This quick tip comes courtesy of my wife, Mrs. Miler:
One of the perks of elite status at some hotels is free bottled water. This may not sound like much until you look at what the hotel charges for the bottled water from the in room honor bar. So, what do you do if you’re thirsty and thrifty, but not elite? Simple. Bring an empty bottle (or a couple of cups from your room) to the hotel’s workout/exercise room. In virtually every one, you should find a filtered water dispenser, so fill up! If you’re lucky you may even find complementary apples or other fruit.
