FWIW - I WAS able to change without losing them. I didn't ask, and customer service didn't volunteer. However, I was only shortening my stay, not changing it.
HI Mary - I was able to get one certificate applied to a booking in August and waiting to hear back about 2 other bookings. So far, a savings of 450 euros.
thanks!
