Yes, daily parking rates are available to all.
Yes you can park your car at Loews Hotel during trip without staying at the hotel I did. What you do is join Park and Chirp online (free) to get a very very low rate. You go through them to get the $6 per day rate very easy and it is pre pay with your credit card online.
Call the front desk. Parking is $30 ish per day and I recall that you can make an arrangement.
Only there for three days...sorry I can't help. Rod (above) has good advice.
Don't know. You need to call the hotel.
