Hi Jo. The forum can help with independent. Many of us only do it that way... and we have probably seen just about every mistake you can make between us all.
Confidence is another issue - I so understand when people feel they need the "safety net" of a Tour Operator when spending all of their spare money ("spare? spare money???" We haven't got any! Have you??)
The extra you pay works when you have no idea of where you are going and want to spend your time and arguing with reps, which is a complete waste of time and money in my view.
If they are going with yous, they don't have to worry. Like us, you know every street, every taverna, every waiter every barman (and in my case the gorgeous Hanna in the Coconut too) and will totally enjoy if they understand the following:
Arillas has something for everyone. Festive teenagers (like me and Sandy - I might be recycled but what's wrong with that dear?) superb meals in dozens of venues, a superb beach, peace and quiet, masses of flora and fauna, Eggy? The list goes on.
Anyone can find happiness there if they make the effort...
Phil
