 I actually booked my stay for July 2016 and for some health reasons i had to reschedule my trip to sometime later during winter I contacted booking and the hotel thru booking to amend the dates but they refused I was disappointed and i thought i will have a better reply Note that the amount was taking after confirming the booking yes i know that my deal was nonrefundable however there is always a chance to be helpful and cooperative i was only asking to change the dates not to cancel the whole booking 
No Positive
