Villa Rental - Best value for money location?

[shakotan]

Both sides of my family [genetic and step] would like to have a bog get together, somewhere abroad in one or two villas.

As not all of them are 'well-off', we've decided a week, somewhere with good weather, and in reach of budget airlines is ideal. 12-15 people total.

What are you suggestions, please?

We're already looking at Mallorca and Southern Spain.

Thanks in advance.
