However embarrassing the tourists' questions might have been, the Telegraph itself should be embarrassed by a repeated typographical/spelling error in the article.
After first spelling "Isle of Wight" correctly not once, but twice, the article later misspells it as "Isle of White" -- not once, but twice.
See for yourself:
A young visitor to Queen Victoria's summer palace Osborne House, on the Isle of Wight, was told that she had nine children and asked: "Did they all have the same dad?"....
"Is this where Sharon and Ozzie actually live?" - a visitor to Osborne House, Isle of Wight....
"Did they all have the same dad?" – a visitor to Osborne House, Isle of White, who learned of Queen Victoria's nine children....
"How long does life membership last?" - a visitor to Osborne House, Isle of White
