A subsequent change is not possible due to system limitations.
Here's the best way to proceed:
Check availability for the desired new travel dates.
Cancel your existing booking (observing the deadlines).
Make a new booking with the correct details.
Important:
Due to dynamic pricing, the new room rate may differ from the original price.
Free cancellation is only possible within the deadline set by the hotel.
