It is nice for the extra space, but I don't know if I would have paid for it. It all depends on how many people you are taking and how the math would work out on two regular connecting rooms. We were upgraded to it last December. It has the regular room with two queens on one side, same bath room and desk as the regular room. On the other side there is a Murphy bed, which is a full, but it is rather uncomfortable. Two chairs, same desk and chair from the other side, same bathroom and same TV but this one has a DVD player. Having the room means more closet space, an extra bathroom and some more space in general.
It totally depends on how many people you have in your group. If it is just a family of 4, book a regular room, you will not be spending enough time in the hotel room to make it worth the extra. Don't get consumed by the name of a Jr. Suite, it is not like it is at a W or national chain.
Have a great time!
