Group reservations can be made through the Booking.com website, provided the booking is made at one property.
Properties provide us with their inventory, and this is what's available for you to book. So, for instance, if you need 30 rooms and the selected property has availability for requested dates, you can make a group reservation.
However, some properties have special rules and policies about group reservations, that's why we kindly ask you to pay attention to the policies and the 'fine print' section in the particular accommodation page. You can always communicate with the accommodation directly and provide them with the additional information.
If the policy of the property is not strict (free modification/cancellation till xx date), you can make a reservation for 1 name and modify your reservation (provide guests names) later, but before the deadline.
If the reservation is non-refundable, this will be evident in the booking process. Please note: if you choose a non-refundable property, the credit card you pay with can be charged anytime in advance.
