I have always found it better, both for myself and the SP to book a hotel at a higher class place.... Not anything fancy but the Raddison or the Holiday Inn.
Less questions from the desk and less "heat" overall.
Also, I find that if you splurge for a better place, your SP is more likely to go the extra mile for you....just like any real date.
Cheers,
Tony
PS. You can also avoid this by visiting a girl at her place of business...like looking for an incall service which allows you to avoid hotel or motel fees.
