Yes E Cork, having significant disabilities/serious illness/pre-existing conditions is an expensive business, but because of those reasons, good travel insurance is far more important for us. Sad but true.
I had a six day trip to Vegas last year, and my insurance wasn't far off three hunderd euro!. Horrendous i know, but you just can't buy peace of mind!. Had a ten day trip to Paphos, Cyprus earlier this year, and my insurance was a hundred and twenty euro.
Best of luck!... At least AllClear phoning you will save you the cost of the phone call!.
