Hi, I live within 20 miles of Weston Park, so no issue for me, however, there are hotels nearby but not within walking distance unless you want to start out very early! best options are Premier Inn at Newport, Days Inn at the services J4 of M54, Premier Inn Telford Town Centre, or various independents in Shifnal, Newport or Telford, failing this, I understand they do camping on site.
Book early at the hotels as rooms go quickly, good luck and enjoy. You could take a taxi if you are imbibing during the day, or ask the better half to drive back, after you have shown her the way to the show! maybe that might be a step too far if you are treating her.
