<human>: Summarize the given text in a few sentences.

To start - this is one of my closest friends. Her wedding is set for June 21, and she asked me to be a bridesmaid a while ago. I am also getting married the same month (June 7!!). 

At first, she was planning a local wedding, but she began to get very stressed out during the process and decided to go a more non traditional route-- a destination wedding in Vegas. I was supportive and agreed to still be a part of her wedding party.

I'm now trying to plan my weekend trip there. Her family booked nice suites in the Palms, did not even offer to reserve a block of rooms for any sort of discount. And yesterday, she texts me complaining that her FMIL is upset that they aren't planning on paying for the reception dinner. I pointed out that it is against wedding etiquette to make her friends pay for their own dinner after flying across the country. I think she's a little mad, but she asked for my opinion.

The thing is, I'm having to go on this trip by myself (without my brand new husband), because we can't afford for the two of us to take time off of work (given we have our own wedding/honeymoon in the same month). The weekend trip to Vegas (hotel and airfare alone) is looking like it will cost me over $600. 

What are my options? Brides, if you were planning a wedding and a member of your party had to drop out for financial reasons, would it cause a riff?
<bot>: I'm in an expensive destination wedding just two weeks after my own wedding. It's just too much of a financial burden. Should I just pay up and make the trip, or back out now?
