Monterey bay aquarium is a nice place and a must to visit if a visitor to the peninsula. It is nice, friendly, great exhibits BUT OVERLY expensive (I think around $15-$20 per person) and VERY busy on weekends to the point that I'd stay clear of cannery row on any weekend day.
It is a fun place to bring young kids though on weekdays for a day out. My toddler loved the fishes, sharks and there is also a small play area for toddlers to explore themselves.
a fun place once in awhile or on a rainy day but to me it didn't live up to all the hype that people gave it before I lived there.
