Yes. I booked a 15 night stay this summer. Then when discounts came out I couldn’t modify it and got cut off from phone person so I booked two contiguous stays for the exact same dates at the same resort (had to break it up since you couldn’t get discount for longer than 14 nights). We basically had two stays at the same time with the same people at the same resort. No problem at all. I then cancelled the non discounted stay.
