I think MSCC are trying to create a standout event. They need I understood 150 attendees which given > 4k members seems possible. I hope it works out for those members who feel it is for them & the organisers who put in so much work.
(I only quote John above as I needed the numbers confirmed, it's not a criticism of his comment)
It seems a bit daft (and elitist ?) that something as important as a 75th anniversary of an organisation with over 4000 worldwide members has only 150 hotel rooms for attendees who want to stay for the proper event.
We've done lots of Mogs over the years and the ability to book the extras by choice was great
The MMC 100th was amazing, felt very inclusive and there were literally 100's of Mogs in the car park each day
