Planning destination bachelorette - How to find location?

Honestly I think you just need to have a conversation with them and decide on a town and then from there decide what you are doing. Usually the bride doesn't organize the bachelorette party.

These are all major airports and you can go anywhere including international. Finalize 2 or 3 vibes that are different say nature (beach, mountain, lake) vs city. Pick 2 or 3 main events, all other times are meant for wandering, relaxing, eating. Pick 2 hotel options in each location at low- middle, or high cost. Present to other bridesmaids and then discuss best season for either location.

If you are the bride, it is unseemly to plan yourself as that puts pressure on your friends to pay to spend time with you. Let the bridesmaids plan this trip using the guidelines above. After a decision is made, then the bride can relay her schedule. Whoever can make it makes it. If you are the bride, I'd keep other costs low. Wedding parties are averaging $1-2k average to be part of weddings these days not including optional gifts.

Am I missing something? Why do we think OP is the bride?

Anyway, I like LM's suggestions. Pick several locations, venues, and accommodations, and see what everyone thinks. Maybe ask them for some suggestions, too!
