We just did DP and stayed in one of the castle club rooms at the Disneyland Hotel--we had amazing VIP treatment, including unlimited "VIP Fastpass" with our ticket, and wonderful service. I'd take the money that you'd pay for the escape and put it toward a castle club room. You have a delicious breakfast buffet included with characters, a yummy afternoon tea, and that great FP access. We had a blast and can't wait to go back. The Disneyland Castle Club rooms have an elevator that literally lets you out right at the entrance gate.
I would pass. We just did the Seine that included the two days in Paris. The hotel isn't very nice and I don't think it was the best way to see Paris. That being said we loved the river cruise part of the trip
