Discount code PROSYS for 25% off the flex rate at the following properties in Spain/Portugal:
- Hilton Diagonal Mar Barcelona
- Hilton Madrid Airport
- DT Lisbon Fontana Park
- Boeira Garden Porto Curio

Don't know about the validity. Got a flyer with the code about a month or two ago. Used it last week. For a short-term booking, there was some saving over the Dream Away rate.
