I am reading more and more reviewers who say the service on board various ships across many cruise lines is not up to their expectations.  Do you think that travelers are expecting too much or is service really slipping?

On my last two voyages on HAL which were back-to-back cruises I saw a difference in the level of service between the two sailings but I will still satisfied with the service on both cruises. 

Do you have any suggestions for improving service?  Are the crew members not being trained properly?  Are their not enough crew on the ship? Do cruise lines need to raise prices?   Are you satisfied with the level of service?
