Anticipation is one of the great things about any journey.
It's like double-dipping on the "happy glow" of a holiday buzz: you get to enjoy the holiday (of course), but in the weeks or months beforehand you can warm up by researching your destination or even just flicking through photos online. For a third dip, we've got warm-fuzzy memories after the trip is done and dusted.
In fact, through the joys of early anticipation and later rose-tinted memories, a disappointing holiday might come to be regarded as a triumph.
