Overnight hotel included with business class ticket?

I am booked SEA-SIN-MDC round trip, business class. On both legs I have a 16 hour overnight layover at SIN. My travel agent mentioned that I should ask if a hotel stay is included with my ticket, since it’s a long overnight layover. I couldn’t find anything definitive on the website. Does anyone know if this is true? And if not, any recommendations on best place to stay for a 5pm-9am layover?

EDIT - Looks like it’s a no, but I will confirm with the airline as well. Thanks to all who replied with helpful information on this!
