Fill in the Blanks Giving advice/WarningsOnline version Fill in the blanks with one word. by Evgeniya Gapon 1 Watch out the taxi drivers who to hang around outside the airport . Make you find out how much the journey is supposed to cost . Don't get until you've agreed the price with the driver , or you could find that you have to pay three or four times the amount you should pay for the journey . You'd leave plenty of time . Be careful you take trips into the jungle . Whatever you , don't drink the water . The most important thing to remember to hold on to your bags .
