Jim, it differs. When I see (or guess) that the dynamic range between the darkest and lightest part of the picture is to extensive, I bracket 3shots to +2/-2 in order to HDR them later . Usually +/- 1/3 to 1.1/3 stop using 2 shots for BLENDING in PS.
Actually I later use only 1 picture out of 10 for HDR or blending. All others are practically a waist of shots but taking them for 'Just in case'.
As I'm using for these shots (i.e. Angkor Wat) my tripod @ 99% I use 2 different custom settings on the 'Mode Dial' knob on top of my camera 5D MII:
C1: f11, ISO 200, Bracket +/0/- 1.1/3, One shot, 2sec selftimer
C2: Same setting except: ISO Auto and 'continuous shooting' (stops after 3 shots bracketing)
Starting with these setting I can easily adjust whatever I want in a blink of an eye.
Some more info about Angkor Wat. There are guides available everywhere. They know everything about the history of these places. And there are PHOTO guides for hire. Beside the history they know exactly at what time of the day you should shoot at what location because they have an incredible knowledge of 'whre's the right light'. And of course they bring you to these places.
In case you need good photo guide I can recommend one, speaking very good English.
Under this web page:
www.peaceofangkor.com/ you can check a guest house run by the owner, David from England. David is a brilliant photographer with lots of pictures of Angkor Wat all over his place.
As I understand he's no more available for a simple trip to the Angkor sites. He send me with one of his guides (Freelancer) to all places and charged me USD88 for2 days incl. Tuk Tuk and driver.
As I like David very much and enjoined talking to him about photography, his guest house was not really my 'cup of tea'
That's why I recommend this guide only and he will charge you only 25USD a day what I see as a more then well spend investment.
Beside that he is more than happy to carry all your gear or only parts of all day. So, do not hesitate to take your 70-200 as well.
Sure you was there before and have your own travel schedule I just want to inform you about my own experience from April 2011.
Don't hesitate to contact me for any more information.

Take care
Hans
