While I think taxes/fees are getting out of hand and are often misused, hotels do the same things here and it was mentioned earlier.

Book any hotel/motel and there is often a bed/lodging tax that anyone staying there pays. This is in addition to sales tax and any other local taxes and often add up to 15% or more. We stayed in a hotel earlier this year in a large US city and in addition to the 15% tax there was also an additional tax of $5/night for state transportation projects. This is also done to fund sports stadiums and other projects.

Taxes are often about letting others foot the bill for goods/services they don't use.

Below is the approx. tax for a hotel room in Atlanta GA. 16% PLUS $5/night.

"Estimated Total Tax: 16% per room per night.
Estimated Total Tax Amount (in addition to total percentage tax if applicable): 5.00 USD per room per night."

Not our island/country, not our laws. We can either choose to continue to go there and pay the new fees/taxes or or stop doing so. Personally, the high cost of airfare from anywhere other then the East coast will do more to hurt tourism than a $5 tax/fee or a 4% tax.
