Next planned trip to Amsterdam 26th May

Just started to book a trip to Amsterdam for 4 people, check out used these the last two times and the service has been great, i would hate to get to the hotel and find that there is no hotel room booked for us, thank god that has not happen to us.  I always phone the hotel 1 week before we arrive just to make sure it’s all sorted, I would always check the hotel reservation if the booking is going through a third party web site.
