when you say a sparkle clean is this work being done after the students have left and before the guests arrive or is it just a clean after guests have left ready for students returning.
The reason i ask is if it is a clean after students leave then expect a lot worse than a sparkle clean, rooms will have bags full of rubbish to remove the bathroom and showers will need a thorough degreasing you wont believe how bad they are left and if kitchen areas are included then expect to spend about an hour and a half on each cooker even after parts have been soaked in a dip tank.
If you require more details on time scale feel free to give me a call my mobile no is on website
