Mention your hotel experience when applying for the shop. Yes, Coyle takes time to schedule shops sometimes. Maybe contact/email the scheduler directly. I started with hotel shop that was in unpopular/international location; I had restaurant and call shops by then with Coyle so I already had a history with them.
Hotel shops do not require cash, only for tips or to oay bar tab. Sometimes they offer “easier” hotel shops for first-time hotel shoppers; maybe try those. Also, they offer travel allowance if the location is not popular ir hard to find a shopper. But don’t give up, you will get one hotel eventually and then it will be easier to get more.
