The entire business model of "resort fees" is to be able to advertise a low price on aggregation sites by hiding/obfuscating a significant portion of the total price. Of course it is deceptive and annoying, but companies have realized the additional revenue far outweighs the complaints and possible lost reservations. It's a shitty situation that nobody likes, but honestly in 2023 if you are booking any type of reservation online -- including the hotel's own site -- you need to read some of the small print. Complaining online on forums like this is meaningless. The only way to "fight back" is not to book, which may mean skipping the vacation, as much as that sucks. Hotels and travel sites have had record revenues and resort fees and have only increased and become more widespread in the past decade. The trend isn't going to reverse on its own while people continue to book at record rates.
