the best advice I could give you is to cancel if you have a reservation on the VOYAGER OF THE SEAS.
There are a lot of problems on this ship
during our cruise they didn't heat pools !!! (economy !) and closed 4 hots tubs on 6, they said they had to fix it.. they opened it the last day and HOT TUBS didn't work (no bubbles)
we were near the city and it was easy to visit amsterdam alone
a lot of this to do in this city
it was a very pleasant city, the ship is near of the old city
we stayed very far from the city, taxi are very expensive
we had a very good time in Gibraltar we went to the top
monkey are funny
the ship didn't stop at Lisbon, we were very sad
