If it becomes less expensive to travel overseas from the united states, american tourists will benefit from the fact that -tourist sites are getting crowded and dirty. -the us dollar has become stronger. -prices of foreign goods are rising. -the us dollar has declined in value.

The answer is the US dollar has become strong. The way the question presents the US dollar is on a global scale of becoming stronger. As currency exchanges fluctuate from currency to currency on a daily basis, this question examines it as a general idea, so presented here as a general idea with an example, only hypothetical, but to demonstrate the point.

A weekend beach trip in Mexico this year costs 500 pesos. Two months ago, I needed 100 USD (U.S. dollars)  to get 500 pesos. The dollar has gotten stronger, so I can buy more. So move to the present time. I only need 80 dollars to buy 500 pesos. This is an increase in strength of the dollar. Strength is an increase in buying power.
