The last train station is at SLS, the Lux tower wing where we stayed at, it was easy access for us to get on this train. Bought 24 hour passes, got on the train to get to The Linq, it was so fast and convenient, much better and cleaner than taking taxi. There was barely any people on a Sunday.
I like to take the train during the day, It was a lot of fun for me, just need to remember to wear flats next time!
