What doesn&#x27;t make sense about it? I&#x27;m spending an extra $900 to be able to afford a vacation I otherwise couldn&#x27;t. Suppose some friends are going on a trip and I&#x27;d like to go along; suppose the Olympics are happening; suppose I want to do a trip while I&#x27;m still in my 20s; there&#x27;s plenty of time-sensitive situations in which an extra $900 is worth spending to allow things to happen sooner.
