I stayed at the Pittsburgh Sheraton on the river, right across from the start of the Three Rivers Trail. A good experience. Easy to get across the river via the bridge right there. I rode there in the dark at around midnight, due to a very-late Amtrak train. No issues at all, maybe a 8-10 minute ride? The next day was a workday (Friday), and it was no problem to ride from the hotel to the Point and then back via surface streets to start on the Three Rivers Trail.
