I'll be staying in Paris (my first time!) towards the end of March with my wife and I'm trying to decide between the PH Vendome and PDG for 3 nights. I only have base status with both Hyatt and Starwood, unfortunately, so I think my odds of being upgraded to anything beyond the standard room is basically nil. Interestingly, the cost of the nights that I am there is only $759 per night for the PH Vendome (I was under the impression it was much more) and $1089 per night for PDG. However, I will be using points for the stay regardless of which hotel I am at (170k Starwood and 200k Hyatt).

A few questions I had -
1) for the base rooms, is there an appreciable difference in the room sizes? Not just the square footage but the layouts? Or is this an unanswerable question because each room is different? I'm also not going to Paris with the expectation that we are going to have huge rooms - I know the rooms in general are smaller compared to other places.

2) Which location is "better" for a first time tourist who, on this short trip, really only has time to hit the highlights?

3) How does the PH Vendome compare to Park Hyatt Istanbul (we loved our stay in Istanbul but I get the sense that the PH Vendome style is a bit more classic?)

4) What is the style of PDG? My wife and I loved our stays at Royal Hawaiian and Westin Palace, not necessarily because the hotels/rooms were the greatest but because both hotels have a classy/historical air about them. I have the sense that PDG is probably a much better property than either of these, but any frame of reference comparison would be really helpful.

Thanks in advance!!
