On the way out of the hotel, keep a little extra money handy. All tourists leaving Indonesia from Ngurah Rai International Airport are required to pay an airport tax of Rp. 150,000. That said be advised that it is against the law to leave Indonesia with more than Rp.10,000,000. Departure for domestic travel is also taxed (Rp. 30,000) occasionally this has already been included in the ticket price - but usually you will need to pay this before you can enter the security area at the departure lounge. And if you have any spare change you can always make a donation to the local Red Cross or charity du jour at the airport or your hotel before you leave.
