Well, I did have a hotel I was going to stay at, but my dad is taking forever to book my hotels and it looks like that one is booked solid. I just need a place to sleep for one night for one person that's fairly cheap and close to most of the main attractions.

As far as the train schedule goes. My train gets back to Paris at 9:45 pm on the 26th. Then I my flight to Dublin leaves CDG at 9:30 pm on the 27th.

Thanks!
