If you’re planning a trip to London, International Development Minister Bev Oda has some tips.

Oda was originally supposed to stay at the Grange St. Paul’s Hotel, site of the conference on international immunizations she was attending. Instead, she had staff rebook her into the posh Savoy overlooking the Thames, an old favourite of royalty and currently owned by Prince Alwaleed of Saudi Arabia…

The bill for three nights at the Savoy last June set back taxpayers $1,995, or $665 a night. The government still had to pay for a night at the hotel she rejected, costing an additional $287. An orange juice Oda expensed from the Savoy cost $16.

Today’s math problem: If the government cancelled the F-35 purchase and reallocated that money to the ministerial travel budget, how many more nights at the Savoy could the Harper government afford?
