A guided tour isn’t my idea of a good time. There’s something I don't like about being led around touristy spots with a bunch of camera toting strangers, waiting for them all to come back to the bus late, and eating all together in pre-chosen restaurants that specifically cater to tourists. I’d much rather be in charge of my own trip – maybe getting lost in the process but at least making discoveries for myself.
But when the tour costs less than 20 dollars and includes three days, two nights in a hotel, two long boat rides and all meals, then why not?
