Property owners who do NOT respond are usually inexperienced and poor business persons.

TripAdvisor is the most important review site there is. Most potential guests will research your motel and choose the property that has the best reviews versus best rates. Responses are vital. You will look very unprofessional if you have never responded to a review. Respond to ALL of them.

Promote TripAdvisor on your website. Request guests to supply reviews.

Reviews are only disliked by owners who have poor quality properties. Some people do not improve their properties . They just take all the income and put nothing back..
The public demands certain levels of quality. If you can't keep up then sell your business to someone who can.
