Years ago, we did a Gateway/Globus Tour (Lisbon-Malaga-Madrid). It was an 'on your own' type that they may not offer anymore: Hotels, airport transfers and baggage handling included - no guided tours.
In Malaga we were delighted with the accomodation: We were 3-people and they gave us a suite overlooking the Mediterranean (7-days).
We left the tour in Lisbon to stay with relatives (didn't use their hotel); in Madrid it was a 3-star near Puerta de Toledo.
For our purposes the Gateway/Globus tour was good. We had to pay full price for my (then) 12-year old daughter; but travelling as a threesome and getting put up in suites made it worth the extra cost
Gateway was Globus' low priced tours, probably no longer offered.
