Travel Advice?

LaureeBelle
My boyfriend and I are going on a cruise in November. We've gone on quite a few vacations together, and before we started dating I was an avid traveler with friends/family etc. I'm thinking about getting a travler's credit card. I've been reading a lot about "Travel Hacking" and looking at all the rewards you get for spending $1,000 in your first 90 days (per person the cruise is over $1,000) makes me feel like getting a credit card and paying with that card is the smart thing to do. 
I've never had a credit card, but I'm financially responsible. I've never paid a bill late or over drawn an account. We both have the money for the trip and could pay for it without a credit card. What advice do you ladies have about travel hacking??? Or credit cards in general?
