Wow I can't believe all of the responses this has gotten in the last 18 hours. I don't even know where to begin as far as formulating a reply. I wish I had some more airline miles and/or more time to get some more. It sounds like my best bet is definitely going to be using my Marriott points, possibly for one of their travel packages. Using one of their travel packages would get me airline miles, which I could hopefully combine with one of the other airlines I have miles with in order to get a first class ticket. So I think Hawaii might be the way to go for now, and try to build up our balances for an international trip for a 1 or 2 year anniversary.
Thanks for all of the replies, and any other advice you might have is greatly appreciated!
