Esteemed fellow travelers --
My wife and I plus our 3 kids will be breaking our European travel hiatus with a trip to the Iberian peninsula in summer 2011. We are experienced travelers, but some health issues kept us on short domestic trips only since 2003. Our children are going with us (ages 10, 8 and 7 at the time of the trip) as well as my wife's aunt.
That said... our tentative plan is to fly into Lisbon, do some side tripping there, overnight train to Madrid for mid-country side-tripping / Toledo, through Seville, time on Costa Del Sol / Gibralter - back home. This trip is limited in length to 10 days, so wanted to stay in the lower half of the country to reduce travel time.
I want opinions on Valencia. It would definitely add heft to travel times (4hrs Madrid-Valencia), and would take away from another destinations. One factor is that my wife is an aquarium nut -- and Valencia has a ginormous spectacular aquarium.
Thoughts?
