Most Annoying Travel Fees (PHOTOS)

Whether it's a $20 daily charge for a resort gym you didn't use, or the new $200 penalty for altering your flight reservation, travel fees have an irritating way of surprising us on vacation.

It should be easier than ever to shop based on price given the explosion of online booking sites -- at least in theory. That cheap rate on the screen rarely includes all fees. Without the help of a knowledgeable travel agent or a resource like NerdWallet that compares fees for a given route, it's challenging to calculate your total cost.

Hotels, cruises and especially airlines like this model because fees have allowed them to stay profitable while slashing their base prices to appear competitive. But it leaves travelers frustrated by charges for things like an in-flight soda that, until recently, we expected to be free. And the creative packaging continues.

The upside to consider is that you can still avoid some of the worst penalties if you plan strategically. Read on for tips in dealing with the latest annoying travel fees.
