I'm not yelling at you. I'm making some emphatic points that often get overlooked when everyone starts thinking about musters and hasn't done one before. As
@RaggedAssSecond said, even with the best planning, there is always something you didn't think of and women do look at it differently. They want clean bathrooms and a few more pit stops and a place to eat that isn't a local general store hot dog.
I don't know if you were in the military or not, but most of the guys in this forum are veterans. I learned from the master who is ex-military. If you think

I'm salty or harsh, I can hand you over to him when he reminds me I've lost focus on handling some of the muster details



! Anyway, moving on. I don't think you can have everyone come in for a one day event. It is exactly 650 miles from my house to Fredericksburg. I'm not driving down for one day.
Typically a muster starts on Friday at noon. Most people check in at the hotel on Thursday evening. If possible, the QM and/or their staff, collects money for lunches/fees then, but certainly by Friday morning. Goody bags are given out at check-in, schedules are in there and maps. A few people will arrive Friday morning and check in.
Then at noon or 12:30 at the latest, we are on the move to the first event, whatever that talk/battlefield/museum is and we go till late afternoon. Then people go back to the hotel to freshen up for dinner, usually on their own for Friday but people break up in groups, etc.
Saturday starts at 8:00 sharp - we are out the door and heading to whatever the main events are for the day. Something in the morning and something in the afternoon with lunch being delivered or however it is being handled.
Members dinner in the evening at a restaurant with a raffle.
Sunday - Starts at 8 sharp, we move out to whatever the morning event is. People also make checkout arrangements, if they are checking out that day, with the hotel. Usually we can leave luggage in the War Room or they have a baggage room that is locked up. At noon the muster is over. Now, some of us stay till Monday because of flights and stay over at the hotel and continue on with the a battlefield thing but that's up to us.
Also, during the muster, someone on your staff needs to start a "Going Live" thread on CWT and keep putting pictures on with what everyone is doing at the muster. Always make sure you have your charging cord with you!!!!
No one is saying you can't do it - those of us who have done it are telling you how it needs to be done for the most success. We are just being honest about the time and money commitment and the fact that even with the best plans, something unexpected will still happen so you still need to plan for that! Guides get sick, staff can't make it suddenly, places that you thought were expecting you suddenly forget a group of you were coming, that sort of thing.
A number of people that come to these events do have mobility issues now so golf carts, whenever possible need to be arranged for in advanced, or they, at the very least, need to know what the walking issues are they will be facing. And again, this all falls under the heading of predictive hospitality.
