Dear Sir/Madam,
I've completed the booking process on Booking.com. Please discard the unpaid #Booking ID : 15706.
Due to a previously unconfirmed schedule, I've made 3 reservations of 1 night on Booking.com for 24, 25, and 26 night. Could you please assign me the same room for all three nights? Thank you.
See you tomorrow evening.
