Certainly, ride there and back if you want to. I'm planning a trip where I leave in a few weeks (2/17) and tour that area. I think I found an opportunity to go to key west but not turn around and go where I just went. I'm doing a loop from fort lauderdale, thru Everglades National Park to Marco Island, then take the ferry from Marco Island to Key West and ride back from there. Just thought I'd mention in case you don't know about the ferry.
