We have done both and both are amazing! I would go with Greece for next summer because of the fact that Disney has not scheduled these every summer like Alaska. Also, the cost of the Greece cruises keeps increasing at a higher rate than the Alaska cruises. We did a 12 nt Med with Greece and Turkey. Family of four in a deluxe inside stateroom near aft elevators was $10,800, now it seems like it is close to that for just two adults.We are going to take one of these next summer and I am so torn on which one to take. What would you take and why? They both sound amazing. We are looking at 8 night Greece and 9 night Alaska. Thoughts?
