HGVC was just starting their 2013 renovations in the Lagoon Tower during my January 2013 visit. So I didn't have photos of the latest renovations.
Here's a link GregT's 2013 photos that show the Lagoon Tower kitchen renovations -

They replaced the major kitchen applicances (stove, fridge, dishwasher and microwave to black instead of white) and the kitchen cabinets (from white to wood) similiar to GW and Kalia towers. No news when the small appliances will be changed.
JMHO...
If room furnishing and amenities (separate tub/shower, in room washer/dryer, etc)
are more important to you than view/room size then I suggest staying at the Grand Waikikian in the future.
