Only 2 People Attending Bachelorette Party

Just looking for some advice: my lovely and awesome MOH planned an overnight trip for my Bach party in a city located 2 hours from where I live. We are just doing dinner and drinks, and then going to a dance club. My town doesn't have any clubs, and this is the next closest city.

We invited 12 people, assuming not everyone would be available (5 of whom are bridesmaids). Bach party city is home to 4 of the invitees, and the rest of us live in my town and will be able to easily carpool. It's a Saturday, so no one will need to miss work.

I wasn't part of all the planning, but I know MOH included everyone in discussions and budget talks. They settled on a $100 per person price point, which includes all costs for the whole trip (hotel, dinner, drinks, uber to/from club).

The party is in 3 weeks, and my MOH has just broken the news that only she and a friend are coming. Everyone else RSVP'd no - no one has talked to me about it, so I'm not sure reasons, etc.

Would you guys still have your party even if it's only 2 people? I just keep imagining myself in a dance club being sad that we have such a small group. I had hoped for a "girls night" vibe with a bigger group, at least for the dancing part since I never get to have a relaxing, let loose type of evening.

Thoughts?
