My mother lodge meets in December just a few days before Christmas, and each year the meeting is followed by a 'white table' dinner and dance (so partners, children, family, friends etc are present) on a ship that makes its way along the Thames in Central London. We go past the Palace of Westminster, under Tower Bridge etc - it's a lovely evening and I look forward to it every year.
Ha, no. We meet in one of the Lodge rooms up at the UGLE headquarters building in Covent Garden. That's about 15 minutes walk away from the pier the boat leaves from, which is right in the shadow of Big Ben as it happens...
