We (2 adults and 2 kids as a family) will arrive Seville via Madrid on Feb 28th and have to stay in Seville until 5th of March.Then have to leave Spain on 9th from Madrid.

This is our first time in Spain and we do not speak spanish...

I am trying to find out:

1-what kind of transportation will be cheaper and easier; take train, plane or rental car from madrid to seville and travel around seville than come back to madrid and spend 1-2 days in madrid.

2-I am a celiac which means I have trouble eating flour and starch and anything made of them...So in seville, we booked a hotel whoes kitchen promised to help my diet but I have to find diet friendly places to stay around seville and madrid

3-Best places to visit with a 6 and a 17 year old!

Depending on your experience please help me out to plan our trip as good as possible ...

your recommandations will be very much appreciated.

Thanks in advance
