Same advice as stated in discussions you may find using the Search button
1. Use the verbiage and formatting they require (third person and specific closing paragraph).
2. Make a schedule for yourself before you get to the property and clarify any questions several days before the evaluation
3. Treat the two night stay as the two day work days and write as you go along - if you wait until the evaluation is over you'll be very hard pressed to complete/submit the assignment by the submission deadline.
4. Bring a guest with you so that someone is enjoying the facilities
5. Prepare for significant cash outlay ($500-$1,500) and have the right denominations with you.
Perhaps start with one night stay first and see if this is a good fit for you.
Good luck!
