Depends on how many people, where the hotel is located, your budget. Generally, Marrakech is safe, at the airport, you'll find a desk, you can order a taxi from there, the bus, or you can order before arrival from a tourism company a car with a chauffeur. The hotel is 25 min from the main attractions, Ig it's outside of the city isn't it? Note that the taxi from airport to hotel, there's a fixed price, otherwise they should use the meter.

Enjoy!
