I went to Spain a few years ago, and loved it! It was not on my travel list however my daughter(Paige) was doing the study aboard program in Salamanca Spain, so i just had to visit! It just happened my other daughter (Lynsey) just graduated with her undergrad so why not go to Spain!
I recommend booking a flight with Delta and selecting the Delta Comfort seats, we had only 2 seats in our area so that was very nice.
As I often say with travel "mistakes were made" this was no different than most vacations and they are great learning moments. For example when traveling in Europe do not over pack, you are moving that suitcase off planes, trains and buses! Someone in our group took the large suitcase (not me)! And when you arrive after your overnight flight do not go to bed! Yes we did, on the plus side I booked a hotel so when we arrived we would have a room. However napping all day was not really my plan! Another mistake was booking a hotel with a shuttle but not knowing how to contact the hotel, and the taxi got lost! Okay a few more mistakes were made but I do not want to spend the time on mistakes.
We arrived in Madrid, slept, then headed out on the bus the next morning to Salamanca which is a beautiful place with so much history (like all of Spain). I loved the hotel we stayed at because our balcony was huge, more like a deck, and views of the cathedral!
Then off on the train to Madrid, then overnight train to Barcelona, now that was an experience! I loved Barcelona, we did the bus tour which basically kicked us off when they were done so we had to figure out where we were. Lots of walking, lots of drinking amazing wine, and you can't forget the food!
