Sj with toddlers??

We will be in jan Juan 1/2016 our babies will be 19 mos and 32 months old .. We will have our teens with us as well, and thought about having our 18 year old daughter just watching the babies so dad and I can get off the boat for a few hours and then coming back and switching ... I haven't been able to really find anything for us all to do and we r only in port from 7 to 2 .. Do you guys suggest anything ?

Last time I was in San Juan off a cruise ship my daughter was 3 (years, not months, you can convert that to months if you want lol). I had an umbrella stroller with me and I toured the forts and the city, and from the pictures I looked at from that trip, it appears she slept the whole time, lol. I don't know if you plan to bring a travel stroller or not, and you have 2 kids instead of one, but it was easy enough for me to do.
