I´ve found the best way to get back to your hotel in any counrty, and this tip is GOLD!!
Every hotel has its own stationary, most place a scratch-pad next to the phone in your room (others have compliment slips at the front desk). Put one sheet in your Wallet and one sheet (from experience) in your back pocket. Then rollon 4am when you get into the taxi trollied (hell, you probably can´t even speak english by this point anyway). just give the Driver your slip... job done <:)
