Sorry all that I fell off the thread.
Here's what ended up happening:
The bridal party had several meetings about proposing options. After speaking with the bride, the maid of honor decided the best option would be to go to Joshua Tree. A place that is entirely across the country, not near an airport, in the desert, in the middle of summer, for a weekend. My wife politely (and honestly) stated that she already had plans that she couldn't change on the weekend that they chose, but also that she wouldn't want to do that anyway, for the above reasons (we've been to Joshua Tree and love it, but this plan just did not make sense). Only two girls said they could attend, and in the end my wife got a text from the bride saying that she was cancelling the bachelorette since nobody could make it.
It feels a little sad, but they could have easily decided to just change the plan to something more accessible like a drag brunch in NYC, or a weekend at the beach ¯\_(ツ)_/¯
