Just the lack of availability of reception staff and their extreme rigidity.
I had booked the stay with credit card imprint + as for all my trips, check-in three days before.
Credit card authorization request on arrival. Weird ...
Except that my bank (CREDIT MUTUEL) systematically blocks the cards when first used in the United States (cause of frequent fraud risk). Imbroglio, I did not understand why my card did not pass, hotel refusal to give me my room. My husband's card (itou CREDIT MUTUEL) blocked. We received 1 / 2h after our arrival a mutual credit SMS: we contacted them and the card unlocked. It's all arranged.
On the other hand,
- why so much rigidity when I had checked in?
- why the hotel charged 100% of the stay on arrival when they had to make a simple authorization?

Not extremely serious, but just regrettable.
