Review summary

Thorough support and communication
Marty provides detailed walkthroughs and is available for questions. Donna is responsive before, during, and after, accommodating last-minute requests, and offers helpful tips.
Drives smoothly, easily, and reliably
Renters found the Cocoon drives smoothly and easily, handling like a standard car. It's reliable for long trips, even through mountains, and performs well.

5.0Spent a week in Acadia, van had all the features needed. Heat worked great for those cold mornings. I’ve researched and spent time in many different vans. It’s clear that Marty and Donna love their van, and have thought of everything. It far outperformed others. Cocoon is well designed and easy to use. Donna quickly communicated, and Marty explained everything very well.

5.0Donna And Marty were very responsive before, during and after my van rental. Quick to respond to questions. The cocoon was everything I hoped it would be. Everything you could want except food and clothes was on the van. It really cracked me up when I opened the utensil drawer, and saw poultry shears and a back scratcher – no really, anything you can think of was on that van. Loved the dimmable led lights, put up the easy black out window coverings, set the lighting to match your mood, and you’ll understand why they named it The Cocoon. I’d rent it again in a heartbeat, except for one thing: we had so much fun, I bought my own camper van!

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!
