There are plenty of ATMs in the airport and throughout the city. I believe all banks’ ATMs do charge a service fee for foreign ATM cards, but I’m not up on the rate. Call us old-fashioned, but we always use traveller’s checks, as I’ve had my ATM card swallowed by a machine twice in my life: Once here and once in the US. It’s a nasty feeling when that happens.
Merchants are becoming better about not charging you an extra fee for credit cards. Almost no one does that now, certainly no major place. However, many people do not realize that credit-card companies often charge a hidden “conversion fee,” which usually takes the form of a slightly disadvantageous exchange rate when they’re calculating your bill. We’ve never found that excessive, though.
My advice is not to change too much money at the airport. Maybe US$100 worth or so, just to get you started. I’ve usually found the best rates in town on Khao San Road, although admittedly I’ve not checked that for a while. No shortage of banks there, and they even have mobile foreign-exchange vans open 7 days and at night.
That’s not a bad area you’ll be staying in. Not too far from Khao San Road, although a little bit of a hike. I see the Airport Bus stops fairly close. If you don’t have too many bags, that might be worth taking. I think it’s 150 baht (US$4.50). The problem with the airport is there are so many scam touts trying to funnel you into their overpriced “limousines,” which are usually beat-up Japanese sedans. At the airport, no matter how official someone looks who walks up to you, DO NOT believe them. Follow the signs and find an airport information counter. And make sure it really is an information counter and not a hotel or private-transport counter. Otherwise follow the signs to the airport-taxi queue and use one of those. You pay the metered fare plus all tollway charges plus 50 baht. It’s not a bad deal, will cost you maybe US$12 or $13 to get to your place. I see the website has Thai writing, so print it out to show the driver.
They’ve started a campaign to try to sweep out the touts, but they’ve only been a little successful. The main problem is that although there are three or four isdentified gangs behind the touts, a very, very influential figure is ultimately behind them all, someone from a Family That Cannot Be Named.
You’ll be in the Rattanakosin area, the original Bangkok, which was founded in 1782. No, this is not an ancient city. There was a sleepy fishing village on this site before then, but Bangkok became the capital and started to be built up in 1782, when they moved from across the river in Thonburi, and even that was the capital for only 15 years.
Lots of stuff will be within walking distance for you. The main drawback to the area is they won’t let the Skytrain or subway into the area, because they don’t want to disrupt the historic ambience, which is laudable. You’ll have to take a bus or taxi to get to the Skytrain, but taxis are cheap here. Flag fall is 35 baht (US$1.05); most places in the central city can be reached for a couple of bucks, $3 at the most. Don’t even talk to a driver who won’t turn his meter on. At tourist sites, you’ll probably have to walk a block over to hail a cab; the ones parked usually want a flat, inflated fee, which is completely illegal. You’re also not all that close to the river.
In fact, except at taxi queues at shopping center’s, it’s always best to hail one from the stret. The way it’s done here is to hold your arm straight out, palm down, and wave it up and down a bit. You’ll see others doing it. (Never ever beckon to anyone palm up; that’s how the Thais call a dog to them.)
I see from the map on your website that you’ll be by the Golden Mountain. That’s worth a look. It’s a manmade hill from the days of King Rama III (reigned 1824-51). Formed when a large stupa under construction collapsed. Rama IV had a small stupa erected on top, and it grew over the years until it’s now the temple you see. Nice view from up on top. A nice walk up, not too difficult, and I think it’s only 10 baht (30 cents) to go up on the roof of the temple.
I also see you are just off of Bamrung Muang Road. That was one of Bangkok’s first streets, originally an elephant path leading to the palace.
