I got back from a stay at the DLH yesterday -- we were able to swim in the "D-ticket" pool (the long skinny one in the middle of the complex), but the main pool (the blobby-shaped one) was behind construction walls. The water slides and the hot tub/sauna were also both open. From our hotel room windows we could see that the main pool was drained, but although I occasionally saw people working in the pool, nothing major was happening that I could see.
There were a bunch of deck chairs and some cabanas set up around the waterslides, and we had a pleasant few hours hanging out. There wasn't any noteworthy construction noise, although there was a tiny disruption from having to leave the gated pool area to use the restroom since the ones in the gated area were behind the construction walls.
