They were very helpful. Paris has a great tourist office, with ll the maps and information you want, and they will book you on tours or into whatever cabaret show you're interested in. AND you can exchange money there. Visit it at 127 Champs Elysee. I just e-mailed them directly and got a response overnight.
Technology is amazing.
They always had pictures of the places and the nominal charge for this service was deducted from the first night's lodging. We also used the TI in Amboise, France and found them very willing to take the extra step and made numerous calls for us. We tried very hard to avoid tourist offices in most of the towns we visited, after a Thomas Cook office recommended a place in London that came complete with an army of ants that crawled all over us in the middle of the night, AND charged us a fee for that privilege. The tourist office charged no fee of any kind. Both offer FREE internet access to surf or do the e-mail thing.
