The most effective first message contains three things: the destination or the date, the people travelling, and the constraint that matters most (timing, discretion, group size). Everything else is handled in the conversation.
A single concierge contact coordinates jet, helicopter, ground transport, residence, table, security and re-flight. You do not interact with each vendor; you interact with one person who interacts with each vendor.
Languages: the concierge operates in English, Italian, French, Spanish, German, Portuguese, Russian, Chinese, Japanese and Arabic. There is no requirement to translate your preferences into anything other than your native language.
