LAST YEAR WE VISITED GREENWICH OBSERVATORY, WE HAD A GREAT TIME THERE, SO I WANTED US TO VISIT IT THIS YEAR TOO. I REMEMBER THE TIMING FO THE VISIT WAS PERFECT, BUT I CANNOT REMEMBER WHAT TIME WE WERE VISITING IT. IT WOULD BE GREAT IF WE COULD BE THERE AT THE SAME TIME. PLEASE IF SOMEONE CAN HELP ME, I WILL BE GRATEFUL.
