In general, hotel pillows are just too soft. I have to double up on pillows normally, but with soft pillows, my head just sinks down like a rock while the stuffing puffs out to the sides like a smothering airbag. Rather than get suffocated in the middle, I try use the edge, only to have the pillow scoot out from under my head while I'm sleeping. I kept waking up and discovering that I needed to readjust the pillow configuration.
My pillows are half and half quilted material and foam hybrids. Thus, they maintain my preferred height while still sculpting to and cradling my head. I worry that I will not be able to replace them when the time comes as I have not seen their type at the store for a while now.
Now, pillows are not very practical to bring on a plane trip. However, they should not pose any problem when driving in a vehicle that only has three people in it. It might mean carrying a bit more back and forth to the hotel room, but I think that the resulting rest will be worth it.
