I've slept in hotels, B&B's, my truck, my trailer, in a tent and even on a couple bales of hay in front of my stall or in our tack stall.
I will only do the hotel thing if I am doing a week long show if I don't have a trailer with a LQ or decent tack room to sleep in with access to someones hotel for a shower. I have been known to shower in the wash stalls at shows though lol.
I have never really had an issue getting sleep unless i've been sleeping in my truck. Otherwise I will sleep pretty sound. I am usually dead beat by the end of the crazy day that I could zonk out anywhere.
