I think your child will love it. I also think that 5:30 is a great time to go to CM's. The p.s.'s haven't been backed way up yet due to them taking some walk ins at opening and some parties who stay for long periods of time. The less wait with a 1 year old the better. I highly recommend checking in a little early if possible. Plus the food on buffets (IMO) is fresher and better earlier in the evening. Have a great time!
