A Family Testimonial from the Summer 2020!

How could we be so unbelievably BLESSED to have experienced this voyage on NS amid such a crazy time?  If you have to quarantine, this is for sure the place to do it! We have all been in awe of this amazing crew-top of the line knowledge, experience, warmth, generosity, talent! From start to finish we could ask for nothing more, except perhaps more time…
