I think you already took a huge leap into doing something others wouldn't even imagine of doing -- that alone is something to be proud of, but like @raj808 said, if you're not feeling it, it's fine to just hop on the bus and do things the usual way, with more convenience.
Yeah, like I already answered to Raj, I decided to buy the ticket to the bus. I guess it came down to this because of multiple factors: my inexperience, my dried fruit ("great idea", yeah, lol) and getting drift into the city center by chance, and cheap hostels.
