Oxygen on river cruises?
 

Do any of the European river cruise lines provide oxygen for passengers who need it? I use oxygen for a CPAP machine, and my portable oxygen concentrator isn't compatible.

You will need to contact the various cruise lines directly. All have different rules and there can even be differences between vessels. So pick a cruise -- then e-mail or tweet or phone the cruise line and ask.

Has anyone requ
ested oxygen on a river cruise?

..... my portable oxygen concentrator isn't compatible...... Isn't compatible -- how ???? I assume you mean it will not run on 220v? All the river cruises we have been on had 110v outlets in the room. Second, can you run your concentrator on a converter that changes the voltage from 220/240 to 110?
