what guests are saying... 

"On-A-Whymm has to be the finest residence on all of Long Island!  The attention to detail is remarkable - outdoor showers being such a treat!  We truly were able to disconnect..."  ~Susan & Jim from North Carolina, November 2021

"On-A-Whymm provided more than the comfort, care, peace & relaxation that were so desperately in search of.  Profound gratitude for going above & beyond as the home owner.  This island is not only beautiful on the eyes, but full of even more beautiful people!  We appreciated it all!" ~ Rick & Katey from Pennsylvania, July 2021
