My boyfriend and I are planning our second NCL cruise this year. We just came back from a May cruise of the Getaway.

For October or November, we are considering the following three options:

• 10/18/15 cruise from London to Barcelona (Iberian Peninsula: London, Vigo, Lisbon, Magala, Cartagena, Barcelona)
  
• 11/1/15 cruise from Barcelona to Barcelona (Western Mediterranean: Barcelona, Naples, Rome, Florence, Cannes, Palma Mallorca)
  

Following either of those a week's land tour of Spain on our own OR

• Same 10/18 cruise (Iberian Peninsula) from above and 10/25 cruise from Barcelona (Western Mediterranean) as a back-to-back.
  

Here are my issues:

• The 11/1 cruise is sooooo much cheaper than the 10/25 cruise
  
• I feel like I might be losing out on seeing other parts of Spain, which was really suppose to be the focus the trip
  
• The back-to-back is a lot more (though I wouldn't have to worry about rental car, food, lodging, etc.)
  
• Is it too many ports in short amount of time
  

Any thoughts? Has anyone done these itineraries?

I'm about to book the Oct. 12 trip on the Jade this weekend. Last minute decision.

Planning a last minute vacation to the Greek isles leaving from Venice. Never having been on either of these lines. Which do you all recommend.

The Magica goes from Venice to Bari, Santorini, Athens, Corfu, Dubroknik and back to Venice.

The Jade goes from Venice to Corfu, Santorini, Mykonos, Olympia and back to Venice.

Thoughts on the ships, itiniraries, anything else?
