We stayed there the 2nd week in December and really liked it. It is definitely not the fanciest hotel around but is more than adequate in our opinion. I think you'll find that, especially with a bunch of kids, the location is just fantastic. It literally takes 5-6 minutes to get to the turnstiles of the 2 parks. The location makes it really easy to go back for an afternoon break or to eat off-site.
As mentioned above, there is a continental breakfast that is ok, nothing too great but serves it's purpose and it's free. There is also a little store for snacks, souviners, etc. There is an indoor pool and hot tub, neither of which we used. They both looked pretty small but that who knows, they might be fine for your group.
As for the room, there was a good size refrig., microwave, desk, 2 beds in the bedroom and a tv. In the living room area there was a smallish pull out sofa, of which when it's open takes up the whole room. There was also a tv in the living room. I think bed preference is very much a personal thing. We found the beds to be just fine. Housekeeping was fine. We missed it one day because our kid was napping. FYI, they do start the housekeeping pretty early and the carts are very noisy going down the hall.
There is a fireworks viewing deck on the roof which is nice. The front desk staff was very helpful towards us and arranged for early check in and called a cab for us on departure.
Other things - parking is 1 car per room, no matter what size of a suite you have. FYI, since it sounds like you're traveling with a pretty big group. ??? The rooms have outdoor entrances and noise can be a factor if someone is sleeping in the living room. We found our AC/heater to be pretty loud. There are quarter-operated luggage storage lockers next to the breakfast room if you have a late departure on your check out day or an early arrival on your check in day. Also, probably doesn't apply to your group, but they have cribs available for $6 per day and having used many hotel cribs, I thought it was one of the better ones that I've had.
There's an IHOP and Denny's next door and a McDonald's a few doors down. There's also a coupld of sit down restaurants close by too.
Overall, I think it's a very decent place to stay, depending on your needs. The location and suites were top priority for us with a little kid (we hate sharing a room with a toddler!). Feel free to ask me more specifics - I'm happy to share whatever info I can remember!
