It is just a half-step above bait and switch for a property web description to simply say "additional fees may exist". I've successfully had fees removed by presenting the property web page description when it doesn't specifically state these non-standard charges.
In today's information age, it's not a technical feat to require individual properties to submit their SPECIFIC additional fees and taxes so they can be seen by web sites(Starwood included) and travel agents. What's the challenge here when, on many travel web sites, we can get room descriptions and rates?? Why are the add-on fees not part of this?
