Need info on a closest hotel from lirr train station pleae
The way to answer your own question is to map the rr station on
and then use the "search nearby" feature on google maps and type in hotels. Doing that for you, the Budget Host Inn is very close but has one TERRIBLE review. I wouldn't stay there.
I don't know what you're going to Riverhead (one word) to do, but you'd be better staying near whatever your activities will be. If you're coming to shop at the outlet mall, the Holiday Inn Express is good, newish and very close to the mall. I hope you realize people in Riverhead mostly drive to get around. You'll be somewhat stranded without a car.
