My late husband had Lewy Body Dementia. Our last trip to Arizona in 2008, which he wanted and I had promised him, was a total disaster. He would leave the RV to go to the rest room (he refused to use the one in the RV) and get lost. I'd be out looking for him--sometimes with a flashlight--at all hours. He was also prone to hallucinations and delusions, sometimes believing me to be an impostor. He sometimes became violent. Compounding the matter were several other serious medical conditions and hospitalizations, where he had to have constant supervision because he would pull out IVs, catheters, etc. I don't think I got more than 3-4 hours of sleep on any night the whole winter so the experience was bad for both of us. Your mileage may vary. I wish you well. God bless!
