OS: We use OS frequently for last minute travel.  Last year we used it 5 times for stays on Maui, Oahu, and Orlando. Yesterday, I booked a 2 night stay at the Grand Islander for late August over a weekend. I like OS because we can book only 2 nights.  For us that comes in handy often. I have tentative plans to use it for Vegas in September.  I always have a back up plan - book a regular hotel.  So far I have always been lucky. As mentioned previously in the thread, I would not buy HGVC just for the OS benefit.
Japanese toilets:  If you are ever flying through HNL go  to the AA club which is shared with JAL on the second floor.  Before you enter the club are restrooms (no club membership needed) with Japanese toilets.  I go out of my way to use those bathrooms because they are the best.  At home they are a must. 
Home bathrooms:  The transformation of primary bedrooms, closets, and bathrooms from the utilitarian designs of the 70s to today's luxurious spaces is remarkable to me. I remember small bathrooms that today most people would consider too small for a closet. Bedrooms have evolved into spacious retreats with high ceilings, large windows, and integrated smart technology (sometimes I struggle too uch tech) lol Closets are now expansive walk-ins with custom shelving, motion-sensor lighting, a hidden cedar closet and climate control. Bathrooms have become spa-like havens, featuring steam showers (love this feature), bidet toilets (a must) , hidden TVs (rarely use), and jetted tubs. Additional innovations I love and couldn't live without include separate water closets for privacy and heated floors and towel racks (the best).  My frugal engineering educated father finds it wasteful. 
I think that is all the topics on this thread.  Fun reading.
