We were also totally impressed with the Hope Lodge. The only thing was that my wife had to clean the room/bathroom/wash sheets when she was done. They supply all the cleaning supplies, you just do the work. Still, it was free. I guess you could figure the cost of gas and compare that to the cost of renting a place if you had to.
If the Dr is planning on putting a peg tube in, it might be less stressful to do it before treatment starts. I didn't start using mine until the 4th week of radiation when my mouth was to sore to eat or drink anything and I lost my taste and apetite.
