Resurfacing 07/25 may not be as big a show stopper as you think if they do it in the same way that City did a few years back. The work was done at night and the rwy remained open 06.00 - 22.00.
Id say your right on the money there Tower Ranger. LDY had resurfacing and an extra 200m added to 08/26 about 2 years ago and all that was done during the night too.
