11-2pm works best for us but I could try and do a little earlier esp if it is the Oakland Zoo. We have a Honda Odyssey so we could fit another mom and two kids (I also have extra car seats) so that we could share gas cost for the longer trips. I also have a membership to the Aquarium I have two extra passes that I can lend out for that trip. There is also My Musuem in Monterey that is great for 2+ year olds. As you can see I am excited about this. If I have a plan for outings and people to meet it will make the summer so much better!! Also we have a pool and hot tub for one of those no cost trips and there is a nice grassy area for a picnic lunch.
