Anyone used -Design Holidays or On the Beach?

[Mamms]

These sites seem to offer decent booking options for Pine Cliffs in portugal, and slightly cheaper - anyone used them or could recommend another ssite that is good?

Not used either of them, but do have a friend who works for On The Beach, so can vouch that they are a legit company. Check that whoever you use is ABTA bonded (and ATOL if you are booking a package that includes flights) and you'll be fine.

Love the look of Pine Cliffs by the way, shame it's a bit out of my budget at the moment!
