Don't forget that there's a lot more than just hotel and airfare. Add a perdiem for food, rental car, tips for everyone from the skycap to the waiter, plus taxes, etc. Go with the highest season rates for the area your traveling to, add in all the other stuff and then add 10% just in case. And of course they pay the whole thing, why wouldn't they??
