The hotel group owns the new £30m Aviemore Highland Resort in Scotland.
Giles said: "We have specialised in the hotel sector for the past 15 years and we're looking forward to bringing our expertise to Macdonald Hotels and Resorts which has a tremendous reputation and exciting plans to grow further."
