Bride/maid of Honor Bachelorette Party

Hi!! My maid of honor has been so amazing so far at being there for me and helping me plan absolutely everything. My bridesmaids on the other hand, have come off as less than excited. My maid of honor and I have thrown out several ideas for bachelorette parties and almost every bridesmaid has an issue with something about one of them, even the cheaper/local ideas that we threw out. My maid of honor is to the point where she thinks she and I should just plan a trip to Vegas and whoever else wants to/is able can definitely join. For most of the bridesmaids, it is not even a money issue, it is weird excuses. For example, one girl is currently unemployed and we are planning the party NEXT April! Several months away. She is saying if she gets a job she won’t be able to take off. It’s understandable, but every time I’ve started a new job, the employer has worked around previously planned vacations. She currently does not even have any interviews scheduled. Has anyone done a vacation with just their maid of honor or what are everyone’s thoughts on this situation? We told the other girls if even staying all night somewhere local and just having a night out doesn’t work we don’t have to stay all night anywhere at all but can all just have a girls night. Thanks for your opinions!
