Also enhancing the guest experience is a pre-arrival service introduced by Dubai-based Jumeirah Hotels & Resorts, which helps travelers by pre-ordering items from the hotel's retail offerings and has them waiting in their room upon arrival. Guests can choose from a range of personal-care products in the Jumeirah Collection - including sunscreen, toothpaste and baby wipes, as well as a selection of books by current authors for entertainment. Orders are beautifully wrapped and left in guests' rooms before they arrive, and the cost of the items is simply added to the room charge.

Memo to other hotels: time to start thinking ahead.
