BEHIND THE DOLLAR SIGNS
The Web site is a good research and planning tool. Those who book online can see at a glance which excursions require a deposit, and which can be paid for at time of entry. However, those who are using the site to check prices should be aware that the prices, as itemized in the package, may differ a few dollars from those you'd pay on your own.
