We are spending spring break doing the National Parks in Utah with my parents. We are flying back east from SLC airport at the end and they are catching the Amtrak from SLC station to Chicago. Its something they've always wanted to do, they are coming over from the UK for the trip. The problem is that their train goes at 3:30am and we need to drop them and we cant stay with them right up til it goes. Im wondering how safe the train station area is at that time of day to hang about, or is there somewhere better and would they easily be able to get a taxi. They are fairly savvy and well travelled but nearly 80 and it is a foreign country.
