Up at 6.30 for the Andrew Marr Show, Sunday. No time for breakfast. Dash to studio. Dash back. Enter hotel. Enter breakfast room. Nice table by window. “Tea please.” Huge meal – full monty. Up to my room, third floor. Can’t find room 3301. Foreign chambermaid says “not existing”. The fool knows nothing. I show keycard. Wrong hotel. Profuse apology. Hasty exit.
