I tried to book an excursion; it was successful until I logged out and back in, when I found no bookings. I emailed Explora, they kindly reserved a spot for us, sent a new reservation document to my TA. The charge for the excursion was added to the final payment due in June. Not to wild about that idea.
I also note the descriptions are lacking; I did find out in this process that when you see an excursion listed twice, that means there are two departure times, even though times are not listed on the website.. I inquired about minimum and maximum excursion size and distance of the hikes; response was they would get with the tour providers and let me know.
There is a consumer virtual event for Explora Journeys on March 23, Aimee Price, Head of Sales USA West and Canada. I signed up, hoping to learn more.
Will post more details of what I have found on the Roll Call page for Reykhavik to NYC.
