This weekend a very close friend of mine asked me to be her maid of honor.  We've been friends for 18 years.  She told me that I didn't need to plan a bachelorette or bridal shower.  I would just need to show up in my dress.  She is in Seattle, WA and I am in NYC.  At first she was thinking of having her wedding in Seattle.  Today, however, her venue fell through and she mentioned that she was thinking about doing her wedding in Hawaii or some such place.  I was looking up airfare from NYC to Hawaii and it's at least $700.  I am working a temp job right now and not making a lot of money.  $700 is a lot for me.  On top of that I'd have to pay for hotel, my dress, hair and makeup, food, etc.  

In response to her saying that she might do a destination wedding and that it would be cheaper, I said that it wouldn't.  It would only shift the costs from her and her fiance to the guests.  After that she seemed upset and said that it'd probably be best not to discuss the details of the wedding until things were firm.  

Was I wrong in saying that a destination wedding would be even more expensive that having one domestically for guests?  I know that this day is not about me, but I really do not have extra cash to throw around.  Should I step down from the maid of honor role?  I don't want to commit such a large amount of cash to an event that lasts one day.  Am I the one being unreasonable?

How can I talk to my friend about this?
