We hired Nick & Amy's campervan to do the NC500 in Scotland and it was perfect for it - plenty of room for myself (6 months pregnant!), my husband and our 2 year old.
Nick & Amy were great at communicating from the start and answered all of our questions as it was our first time hiring a campervan. They've made lots of adaptations, like the seats being able to turn, lots of creative spaces to store things, a great heating system and warm bedding so we had a comfy stay for 9 nights and also a rear/front dashcam which we found helpful on the smaller roads. All the cooking facilities came in really handy. We stayed at campsites every other night, but since the battery charges from the engine/solar panel, we could have easily gone longer.
The pick up and drop off were really smooth and they had thought of everything we needed to know.
We would definitely recommend the campervan for your trip!
