There's an IBIS hotel up just beside the approach to 19L. From there you can walk to the 26 threshhold aswell. There's a Radisson close to taxiway U, which is probably a lot more expensive. Ibis has a free bus-service from the airport.

the Ibis is at spot no 8 basically. The Radisson (or is it Mornington? cant remember) is at spot no 4. I see you're here on weekdays which is good, they're likely to use 19L/01R then during the rush-hours. Usually for landings.

Walking to 01L/19R might take a while. Probably easiest to take the free bus to the terminals, and then catch a normal bus from there, I think its bus 583. I'd drive you around but unfortunately I'm working on those days. Perhaps someone else is out there though.
You might get lucky on the thursday, and get three jumbos, Thai, Malaysian, and Iran (which could be an A300/310, but could also be a 747-100 or 747-SP). Thai lands at 06.50, the cargo comes in even earlier, sunrise is at 3:30 AM
around those dates so you got plenty of light
