We are going to Paris, then London, this coming May. My husband is dependent on his cpap machine and cannot sleep at all without it. In the US he takes it with him, no problem. However, in Europe we are wondering what will happen, even with the converter or whatever. The last time I went even my hair dryer just about burnt up the outlet even with the converter, so we're afraid the cpap might start a fire. Can one be rented in Paris? What would we need to do to rent one? Could a prescription from a US doctor be used? Any advice would be appreciated!

PS These same questions apply to our visit to London....
