Review summary

Accommodating and highly responsive hosts
Marty and Donna provide comprehensive walkthroughs, are always available for questions, offer helpful tips, and accommodate requests like last-minute bookings or safe parking for personal vehicles. They ensure guests feel confident and supported.
Drives smoothly and handles well
The Cocoon drives smoothly, handles easily even in challenging terrain like the Kancamagus Highway, and doesn't feel like a heavy vehicle. Guests praised its reliability, comfort on the road, and off-grid capabilities for extended trips without hook-ups.

5.0Amazing! We absolutely loved our trip, and so much of that was thanks to Cocoon. Having our “home” with us every step of the journey made the experience unforgettable. Marty and Donna were fantastic to work with from start to finish. From the initial reservation to pickup and throughout our trip, they were always available with helpful tips, tricks, and advice that only seasoned adventurers can provide. We’ve camped before, but we weren’t sure what to expect from van life. We completely fell in love with it! The van was thoughtfully equipped, comfortable, and made exploring so easy. All of the van’s systems were simple to learn, and Marty gave us a thorough walkthrough before we left, making sure we felt comfortable and confident using everything. We would 1000% recommend renting Cocoon and experiencing RV/van life for yourself. We can’t wait for our next adventure!

5.0My girlfriend and dog lived in the Cacoon for 6 nights, was a fantastic experience. The Cacoon was able to stay cool for my dog when we went out for hikes and dinners. Bed is comfy, cabin is spacious, overall I couldn't recommend the Cacoon enough!

5.0We had the best trip traveling through New England in the Cocoon. It drives great and has all the things you might need for camping or boondocking. We had it for 5 days and didn’t need any hook-ups at all, just had to refill the water tank once. Donna and Marty were super helpful and easy to communicate with. Definitely recommend to anybody trying to travel through New England this way.

5.0The Cocoon was absolutely perfect. They thought of everything when they built this van. We used it for 9 days and went up the New England Coast then over to the White Mountains. We never even had to plug it in, used it off grid the entire time. It was the most comfortable van ever. Donna and Marty were incredible. They checked on us once to be sure everything was ok and were quick to respond to any questions we had. I would highly recommend the Cocoon.

5.0Donna and Marty were very generous and welcomed that this was my first van life experience. Marty spent the time to familiarize myself with the van (and was available throughout my stay to answer questions as they came up). Their van is extraordinarily setup and outfitted for van life. I'n my opinion its an ideal layout. Donna and Marty thought of everything one might need during a stay, save for supplying your own food. The seats (that convert to beds) were high quality foam and very comfortable. The composting toilet was easy to use and well designed in that it stowed away easily, but was always handy when needed. I had a great time in my first van life experience largely due to this fantastically setup van and home away from home. I would highly recommend 'Cocoon' for a stay. Combine it with Harvest Hosts/Boondookers Welcome and you's have a lovely, comfortable and memorable stay.
