Hi Caz,
I did this holiday in November and think you've made a good choice. The hotel is nice enough and food was buffet style at both breakfast and dinner.
The included excursions are good to some nice places if thats your thing, I liked Ronda best but they were all worth going on.
If you take both optional excursions (Gibralter and Alhambra Palace) you will have a full week with only one free day. Of the two I enjoyed Gibralter but others preferred Alhambra palace its just personal preference, wouldn't have missed either.
On the free day we had some of us spent it strolling around Mijas but others decided to go to Malaga on public transport.
If you get Clair as your tour manager she ivery good and so helpful.
