Hey flymarbles, welcome to the group.
One thing, I moved this topic to this forum on favorite things to do in Spain since you posted it in the "jeremy's multimadrid.com" forum by mistake. That forum is only for feedback on my site and for me to announce new things added to the site.
Oh yeah! A seriously broad question indeed but here goes.
10 days to kill in the south of Spain:
� 2-3 days in Granada :l:
� 1-2 days in C�rdoba
� 2-3 days in Sevilla
� 1 day in M�laga (should be skipped if short on time).
� Day trip to Ronda
Try
www.andalucia.org (in English as well as mnay other languages) for great info on these places.
Also, in my humble opinion 4 days in Ibiza is overkill. There are soooo many better and more interesting places to spend time in Spain if you have never been.
If you are flying out of Madrid, add a day in Toledo and maybe even the last overnight if you can on your way up towards Madrid.
Have fun.
Saludos,
jer...
