I've been pricing fares for a trip planned this fall and it seems more and more airlines are listing the fares with taxes and fees included which is very helpful. However, if you are going to stay in a resort hotel they often don't show resort fees until you are ready to pay. I found this in Puerto Rico where resort fees attached were incredibly hight. One hotel had rooms offered for 290/night, at checkout they added 75 dollars for resort fee, and 25 more for taxes. I have been told that those resort fees can be negotiated if you are just spending the night and don't plan to use all the facilities.
