Hi!
I've stayed at the Cont several times - the only adult with 3 kids and one adult, another time with one teen helper, 1 adult, and 3 kids and we had plenty of room. We've been in both the tower and wing. The sinks are outside the bathrooms which is great for a family. Although I prefer the more subdued colors of other resorts, the Cont is vibrant and exciting for a first visit with munchkins of any age.

Brings back such memories!!!
If in a wing I might suggest asking for a room closer to the main building - shorter walk. Equally important, if not MOST important is to request a room in the north wing facing the monorail. Oh, what a treat that was for my 7 & 9 yr olds to watch the monorial glide right past our room..I loved it as much! Also, we could see the tip of Space Mountain and MK Railroad - it is a dream come true room for first time magic dreamers!
If you have a tower room you might want to request a lower floor (rooms start on the 4th floor) - smoking floor is 8th fl so you would not be too close (unless you smoke and want the 8th fl

. Don't know about you, but we were way up there and I was always worried when the kids went out to sit on the balcony..not that the 4th fl is safer, but it sure felt better the next time we stayed in the Tower!
You are going to have SO much fun!! I did Disney 2wice a yr (winter weekend and week in the summer) myself with 3 or 4 children for many years. I have the most wonderful memories!
Oh, I envy you....it's going to be wonderful!!!
