Answer:
Their previous stay
Step-by-step explanation:
The guests in hotels follow their previous stay trends. There is very least likely that a guest may choose a hotel based on trip advisor comments. It is usually when the guest has no other source of information regarding the hotel, then he may go for comments from trip advisor. If the guest stayed in a hotel and he feels comfortable with the staff and service of that hotel there are high chances he will return to same hotel again.
