Portugal, Spain and Santorini

Are there any 7-10 days cruise that visits Portugal, Spain and Santorini. We prefer to go in April or May 2018. Thanks so much.

Very unlikely. Portugal and Spain are in the western Med cruises, and even those are seldom in the same cruise. Santorini is in the eastern Med cruises. Since most cruises are between 7 and 12/14 days, the distances between those ports are too far away.

Wind Star has a few cruises that go from Lisbon, Portugal to Barcelona, Spain (or reverse) in April/May 2018. As Ine said, those two areas are just not close enough for such a short cruise.

HAL Koningsdam April 21 for 22 nights if you want all three areas. Price is pretty good though for 22 nights.
