We chose the lst because of a few reasons, my dh conference will be over at the swan and he can be with us, we are getting an ap discount off the tickets and on the 2nd we are going to the cp in epcot because my ds want to hear hayley joel osmet narrarate. Its our first one so I really dont know which day is really better than the other. We also will be eating at the crystal palace, I tried for the adr a long time ago and all it could get was like 4:05 pm so we took it, the party sounds like alot of fun. Have a great time.
