Are beers included in the trip’s price?

Yes, the price includes 30 beers per guest for the trip (average of 3 cans per day per person).
You can buy more beer on board if you wish.
Other kinds of alcoholic drinks (whisky, vodka, gin, etc.) you must bring it from some airport duty-free shop before arriving in Padang because they are expensive and not easy to find in Padang.
