We are doing a cruise in and out of Barcelona at the end of January. Upon returning from our cruise on Feb 7, planning on travelling south of Barcelona for about 2 weeks to escape the some of the winter back home. We will be using trains to get to each location. Thinking on 4 nights in Valencia, 4 nights in Seville, and 6 nights in Madrid. Since we have the time, we can sightsee at our leisure. I figured we can take some day trips without having to change accommodations constantly. My husband is not a fan of packing and unpacking too many times I read thru other forum posts and gathered itinerary ideas. Looking for input if too much or too little time in each location.

Some daytrips from Madrid

If it is possible for you I would have longer in Seville (but not shorten your time in Valencia or Madrid, maybe lengthen them too if possible). You only have 3 full days and there is much to enjoy.

There is a lot to see in Sevilla so if you are looking for a leisurely pace I would just concentrate on Madrid and Sevilla.
This is what we did at about the same time last year:
