As early as 9 am on check in day, you could check in early too, although you might not get your rooms until after 1PM.
Yes both...we used the pool prior to check in and stayed later after checkout... Make breakfast/dinner reservations in the main restaurant. If you do go for breakfast have someone snag a good spot in the pool area when it opens...it fills up fast..grab some towels and leave some stuff at a table. There are also two seperate section divided by a big walkway/hall. Both sides cater to toddlers to teens..have fun!!
Around 1pm, before your check in time then check out is at 11, but you can stay the whole day
Not sure about arrival but once you have your wristband, you could stay all day on checkout day because they don't check and checkout is all electronic. I'm not sure what the official rule is though.
