We flew from Khao Sok to Bangkok directly after our night on the raft boat.  It was definitely a shock going from serene and peaceful jungle to the hustle and bustle of Bangkok.  When we arrived we were unable to find an Uber, and were facing about a three hour line in the taxi queue due to a local festival and increased traffic.  Fortunately, after about 30 minutes of spamming for rides, we eventually got an Uber and made it to our hotel.
