The US dollar is in trouble all over the world due to our economy at home. the guest mentioned about 3 years ago, but the rate is really reverting back to what it was about 20 years ago when it was at about 25-27 baht to the US $. There are and will continue to be many factors as to why the rates flucuate. Knowing and understanding these trends can help a traveller decide when to travel to get most out of their dollars. While the dollar is weak, and if you are travelling anyway, knowing where to find great deals while on holiday also helps, there are still good deals to be found if you shop around. hope that helps.
