I would advise using your favorite mileage earning card and then doing a balance transfer to a card with some sort of 0% introductory offer for transfers (and no balance transfer fees hidden in the fine print). There seem to be a number of these out there.

I recently received a solicitation for a Choice Privileges Hotels Visa from Bank America offering a 1.9% APR on balance transfers with no annual fee or balance transfer fees. I can't remember off the top of my head, but I am pretty sure the 1.9% is for the life of the balance... I will pay my transfer off soon, so it doesn't concern me too much. Here is a link to the online offer:

The offer also included 6,000 Choice Privileges points after the first purchase, so I took it to Starbucks and purchased a coffee then put it away because interest on purchases will continue to accrue until the transferred balance is paid first. I don't use Choice Privileges but the points can be exchanged for airline miles (I transferred 5,000 Choice Privilege points for 1,000 AAdvantage miles, which took only two days to go through).

I was pleased with the BofA offer and have been happy with their customer service and website.

Congrats on the upcoming engagement (or am I supposed to say "Best Wishes;" I can never remember)!
