As of the moment I would not order anything from ARL not until they send out orders that they have owed a lot of people for some time now. They still owe me an order from November 2012 and a lot of other people on another forum. They are not even returning emails and I even tried making another order through a different email to see if they would actually accept it which they didnt so something fish is going on there. I always loved all of their oils and my beef all the time with them was the shipping but their quality was always on point.
Whatever season you're visiting, don't take the weather lightly — temple-tramping in the scorching afternoon sun can be a challenge, so come well-prepared. Dress lightly for the weather, but keep in mind that some palaces and all temples (notably the Grand Palace ) have a strict dress code. Also be sure, and this cannot be said enough, drink enough fluids ! You don't have a reason not to, as 7-Elevens and other convenience stores are abundant in Bangkok and they sell cooled beverages for as little as 10 baht. Locals get their water from "reverse osmosis" purified water machines that fill up a one litre bottle for one baht.
