Dawn and Mike,
I second Raoul's comments. There are a number of cruise ships that would qualify as perfect for the over 50 set. But, unless we know a litle bit more about your personal preferences and the cruise experience you are looking for, it is difficult to narrow the field. One suggestion I can make, however, no matter what ship you select - if it is within your budget, opt for a balcony cabin. There is nothing more romantic on earth than enjoying a private breakfast on your verandah or enjoying the solitude of each others company as you watch the sunset.
