We are visiting Paris with my family of 4, my husband's parents, and his sister's family of 4, so 10 people total. The Louvre website says that groups of more than 6 people must make group reservations, and will be denied entry if they do not have group reservations. But then it says that reservations are required Dec. 23-Jan 7.
Can I book 6 tickets for my in-laws and then 4 tickets on a separate purchase, for the same time slot, or will I risk being denied entry because I didn't book a group reservation?
