Abu Dhabi Grandstand Choice

Well, it looks like I will be in Dubai the weekend of the Abu Dhabi Grand Prix. Has anyone been there who can suggest the best choice of grandstands to buy a ticket in? (I guess I only have a few days left to get the early bird discount.)

So far, I've been reading that the top two choices are the West and South Grandstand. (Apparently, the Main Grandstand is good for the start, but that's about it.) They are also offering for the first time General Admission tickets on the infield opposite the North Grandstand. Any clue whether that will provide a decent viewing area?

Any tips on attending the Abu Dhabi GP will be greatly appreciated, including how to get from Dubai to the track, perferably using public transportation. I'd rather not have to drive in the UAE. I think it's about an hour between the two cities.
