We did Iceland/Ireland and Norway Fjords on the Celebrity Apex, sailing from Amsterdam last August. Wonderful cruise with beautiful scenery but not like any Caribbean or warm Med cruise. We did use the hot tubs during sail away from Akureyri, Iceland as well as while in Ireland and Amsterdam but there were not many people in the pool. This was a physically busy trip and we found the evenings nice for relaxing and enjoying the ship (loved the theater format).
