Do the audio guides you rent at the museums come with headsets? Can my husband and I share 1 guide with 2 headsets? or do we each need our own?
In some museums, they come with headsets, in others you hold up to your ear like a telephone. Don't bother with 2...get one and pass the headset back and forth.
I don't know if you have an ipod, but Rick has quite a few audio guides availble for free that you can add to your ipod. This is what we are planning to use when we go in August. Those couple of Euros saved will mean more wine or gelato.
