Hi Sheanna, and welcome.
I haven't done the Lisbon Coast one, yet, but have done Costa de la Luz. The hotel (in my opinion) is very good, nice big rooms, and cleanliness is excellent. The food is really good, and a huge choice. The beach is incredible, although there isn't a lot around the hotel to do. I found it a very relaxing holiday, although the humidity can be quite high.
Seville, which is the only full day excursion, was really nice, plenty to see. If you have any more questions I am happy to answer them. 🙂
