Amenities are few. The free internet, great library were very good.
The food was quite poor. Breakfast, lunch and dinner are all scheduled; during non-scheduled times there was no food available, except hamburgers for $5 for 1 hour on the pool deck. Food Quality: remember your dorm days at college? This is a notch below that. Dining room: they tried hard, but meals took forever and quality was fair to mediocre. Desserts were awful. Room Service: minimal, only half sandwiches available. Couldn't even get a soda!
Swimming Pool: laughable. Only filled while in port, because all the water sloshes out when you're at sea. It's tiny. Only has vertical ladder for entry, so anyone with a disability couldn't get in or out. Not heated. No jacuzzis.
Entertainment: mediocre (they tried hard; their internet guru turned out to have a beautiful singing voice, and she entertained a couple of nights).
Lectures: some better than others, all dumbed down a tad to accommodate the wide range of listeners.
Room design:spartan! We had an ocean view room, but what we really viewed was the deck outside where all the people were walking! So unless we were fully clothed & occupied, we couldn't open our window!
I booked this cruise through Online Vacation Center. They are offering these "Enrichment Voyages" and touting them as "adventurous." They are not explaining the problems with ship motion, and they're glossing right over the quality of the amenities. Our price averaged $200 per day per person. We could have taken a Princess Cruise that had basically the same itinerary at the same time, and that would have been only $100 per day (and obviously would have been a more comfortable trip), but we were already locked in to the MV Explorer.
If you are used to cruising with the major lines, with all the nice amenities and good stabilizers, I think you'll be very disappointed in this cruise. I don't think anybody with a physical handicap (like needing a walker, or using a cane) should be on this ship because the movement made it difficult and dangerous for them to be up and about. And as far as the "enrichment" goes, most major cruise lines now include guest lecturers who give the same information.
