hotel room rates

[Edited to be more specific to France] In France, a hotel occupancy tax of 1-4 euros per person, per day is charged, usually in addition to the advertised price. Was this your question?

Also, room prices are advertised for a certain maximum number of people. For instance, you cannot add extra people to a double room unless the hotel agrees to add a cot, etc. Sometimes, single travelers will get a discount for using the same double room as a single, especially if breakfast was included in the price.

Can you define "daily occupancy rate" for us?

Sounds like a euphemism for "another tax".

Unlike the US where hotel room rates are often a third lower than the actual cost once several taxes are added, in Europe you mostly get what you bargain for. However many areas now add a small per head fee as an occupancy tax. It depends on where you are but it can be between 1 and 4 or 5 Euro a head a night depending on the star level of the hotel. It is often paid in cash in addition to the bill and usually excludes children. I don't recall what it is in Paris but it is a fairly trivial amount.

Yes, that is the answer I was looking for. Thank you all.
