In a word "YES", it's worth traveling for treatment. I sought treatment at Johns Hopkins in Baltimore (2.5 hours away from me). My wife and I were able to get accommodations for free at Hope Lodge. We stayed all week and came home on the weekends but may stayed the entire time. They have a bus that can take you back and forth and in the 6 weeks during treatment, several different organizations and groups donated their time and brought meals.
Johns Hopkins is the top hospital for H&N cancer and I can say assuredly that they are the reason I'm here today.
