It is always advantageous in a busy airport to go somewhere before boarding you plane where you can relax.
The Blue Ribbon Lounge at Ko Samui International Aiprot (USM) is a great little lounge (the domestic side) that has food, drinks and waiter service. I traveled from USM to Bangkok so frequented the Blue Ribbon Lounge by gate 2 Domestic Departures.
The lounge has white painted rattan furniture, good WiFi, two desktop computers and an abundance snacks and even freshly cooked food from the menu.
The lounge is open for business class and also Priority Pass members, along with other lounge access memberships. If you are interested in never having to sit in the general departures area being disturbed by the uncomfortable seats, screaming kids and constant clatter.
