Hi Marvilyn, welcome to "Spain Lovers Anonymous!"
Good Catalu�a itinerary, nice choices for day trips. There is a really nice thread on Tossa by member "Martap" on my board at
www.multimadrid.com/cgi-bin/jersbbucgi/ultimatebb.cgi?ubb=get_topic&f=8&t=000030 in case you want to get even more psyched for the visit
On a Madrid note, there is a bit of a problemo with the Retiro Park as of about 6 monnths ago, the main lake is under some nasty construction making it not such a nice place to visit right now

For details take a look at the thread at
www.multimadrid.com/cgi-bin/jersbbucgi/ultimatebb.cgi?ubb=get_topic&f=6&t=000007 on monuments under cconstruction, there are links to photos in some of my posts there. I will be updating that thread as time goes by but it is not likely that teh construction/renovation will be completed by early June
I would go to Toledo and spend one night, then off to Salamanca for the second (or maybe even Segovia) if you have not been. I think one night in Toledo is enough to soak in its charm
I think that splitting your time in Madrid is a great idea, I would never get down on ya for that. Toledo is a total must see for anyone who is going to be in Madrid for 5 days!
On that
Los Amigos Hostel topic, you really should enter to win the 2 free nights there. You can do so at
MY HOSTELS SECTION HERE (there is a link that says "click HERE to win 2 free nights!" right where Los Amigos is mentioned.
Saludos & Suerte,
