I normally don't sleep well in a tent. I also don't like the faff of camping. Sitting on the damp floor, stirring a bowl of morning porridge. Drying the tent, packing up etc. It's all a faff when I could be riding or just chatting. I've had better experiences and met more people in B&Bs, hotel, rooms, Warmshowers etc. I like a roof and walls. White fluffy towels and a soak in a hot bath at the end of the day is my thing. I deserve it. That said I usually carry a 800g emergency tent and a light down sleeping bag and I have used them. I however must admit , sitting outside a tent on a sunny morning with a fresh brew is one of lifes small joys.
Accommodation for the single rider is a bit expensive in Europe. The odd night in the tent can restore some of the financial balance. But travelling with a partner, it is no contest. A room every time.
