NEWBIE ?

Don't worry if you are a newbie when you are still get lost (no where). you can use google map to know what you must to take ~ but in thailand maybe you can use this link : http://www.transitbangkok.com/ but i think you cannot get a lot of information from there. But it's still quite helpful than you really get lost ~ 

In Bangkok, you can use many kind of transportation such as BTS, MRT, and Taxi maybe (but not recommended) for easier way to go somewhere :)

At the airport you can take a map from department of tourism and get some information (you can ask everything) and you can decide where you want to go and search everything in google maps. And if you want to go somewhere really look near from BTS or MRT and it's still 5-7 kms just take a taxi.

So, I'll give you some tips to go around Bangkok (just what I know now) I'll update soon after I know something more

#1 Grand Palace, I think if you want to know about Thailand you must to go to Grand Palace, It's cost 500 Bath for one people. I think if you want to go to grand palace it's better to take a taxi and you can go somewhere around there by walk (like khaosan road)

#2 Chatunchak Weekend Market, If you want to buy souvenir and clothes and FOOD you can go to Chatuncak Weekend Market or JJ Market, you can go there by MRT (Chatunchak Park) or BTS (Mo Chit Station) after you go to Chatunchak Weekend Market you can go to Chatunchak Green (Food Court) and Chatunchak Park.

#3 If you want to shopping with Air Condition you can go to Union Mall, but most of them are female cloth but if you want to go to mall just cross the road and you'll find The Plaza (Central Ladprao). you can go there by MRT (one stop after Chatunchak Park, Before Lad Prao. I forget station name) or Bus.
