Travel advice: The minute you select your international destination I would recommend that you check to see what entry requirements must be met ( how many blank pages in your passport) and if you will need a visa. Don't leave this important matter to the last minute as it takes time if you require a new passport, or if you must send away for a visa.
About two months or so before the trip, check to see what medications/ vaccines are necessary for optimum health. http://wwwnc.cdc.gov/travel
Also within this time frame go through what clothing you will take with you. You have enough time to add or replace travel outfits and shoes.
Reading travel books and guides while you have free moments will help you better able to get the most from your trip. They can be downloaded.
Besides, consider it half the fun relishing in the prep time. I know I do.
