No Worries. When you line up for immigration--to the left is a bank window--go there first and buy your visa stamp (small green and orange stamp.) I am pretty sure it is 25-30$. Now go through immigration.
Get a taxi from the Line of taxis--DO NOT LET ANYONE OFFER TO CARRY YOUR BAG.
Stay at the Sheraton (25 minutes by taxi.) Extremely western--very very nice. Extremely safe. Everyone speaks perfect english and will arrainge anything you need.
Have a Great Time!!!!!!
