I don't drop my toddler son often. Maybe 1 or 2 times a month just long enough to catch a movie or dinner. So I'm probably not the best review to read if you are looking for an in depth review.
I have never encountered any major problems at this place. He was always fed and given drinks. Snacks there are reasonably priced and they do not mind feeding them snacks I put in his diaper bag as well. Price wise this place is cheap! I can't believe it and they are always accommodating. Cheaper than other day care drop in in other casinos. While that shouldn't be the entire factor on why this place is great, I'm sure it helps most parents.
My son always cries going in ( He is at that stage ) but stops immediately once he sees all the toys and kids. Always comes out with a smile and sometimes needs to be carried out because he is distracted with the retail space.
If you drop your child often enough you will need shots records. At least from my experience. They do operate like a license day care.
