I have stayed at the Condado, my daughter stayed there last month and it is now called the Conrad.

It is on Ashford Ave, and there are alot of restuarants and shops on that avenue.
A short ride from there is Old San Juan, very touristy area lots to see and do.
You can see El Morro, and this is where the ships dock.
You should definitely see the Yunque and check out the bacardi factory.

You should have a nice time, the weather is wonderful that time of year, you should bring a sweater or light jacket for the evenings.

feel free to ask me anything and I will try my best to help you.
My husband is there right now, wish I was with him.
