A Cruise to remember!

My fiance and I are getting married on March, 2015. Both our families are not able to help us financially with our wedding or our honeymoon. We chose to have a small wedding in order to have a better honeymoon. We both work but money right now is very tight. My fiance is basically paying for the whole wedding and honeymoon (or trying his best to get the money to do it) as I am not able to help him either...  :( Part of the honeymoon is a Mediterranean Cruise and wich we booked but haven't paid for yet. The final payment is due by the end of December. Nothing will make me happier than surprise my fiance with being able to pay for that part of the Honeymoon trip so he doesn't has to stress out so much about money!... We want an unforgettable trip on our honeymoon, please if you can help me out to reach this goal with whatever you can and feel like to... Thank you all in advance and blessings to all of you!!!!
