Just one more suggestion...it's where we are staying. It's a little farther away but the ART takes you there. The Residence Inn Resort (technically it is in Garden Grove). It is 1mile I think from the DLR. It has gotten great Trip Advisor reviews...and some friends of ours highly recommended it to us. It's got kids suites with a livingroom, kitchen(great for keeping things cold or a quick snack...I won't be cooking dinners

)and two seperate bedrooms(one for you with a king or 2 Queens and a kids room with their own bathroom, bunkbeds, TV and table. It also includes the breakfast like the residence inn maingate, as well as an evening reception of sorts. This place is pretty new and has a larger pool I believe. I don't know if this is too far away for you...but just thought I'd mention it. With all the researching we did...we did lots and lots....we liked this the best as offsite.
