Getting to Dry Tortugas National Park?

Is there a cheap way to get there? Everyplace I have seen is $150 per person via boat.

unfortunatley no, i’ve been to key west twice and and wanted to go both times but didint ’cause of the price–it doesnt seem worth it considering how short a time you would have there–i suppose if you camped a couple nights at dry tortuga the $150 would be worth it–but its pricy no matter how you look at it
