如何分拆TUNE的空调预付费

All Tune Hotels.com rooms come equipped with a ceiling fan. Each room is also equipped with one air-conditioning unit, however, usage of this air conditioning unit is charged separately from the room cost. You can buy prepaid air-conditioning credit units in sets of either 12-hours or 24-hours either when Booking your room online or at the Front Desk upon check-in. Prepaid air-conditioning units are programmed into room key cards, deducted while in use and can be split up over the entire period of stay. For e.g. should you purchase 12-hours for use over a 2 night stay, if you only use 6 hours on the 1st night of your stay, you have a balance of 6 hours for use on the 2nd night of your stay.
