Went onboard star cruise last year if I remember correctly my dd less than 2 years. If u plan to leave him in the kids club which u need to pay than it's fine. There are no activities organized for young babies/ young tot so we entertain dd @ arcade, swimming pool, walk around, etc. i still remember eating in a place that looks like a school canteen. Have went as a couple on royal c & had left me with a gd impression. royal carribean from what I gather seems better as they have activities for younger tots so planning to travel with them, now with a kid in tow
