Lina, 54, runs hotspot Linekars Group and she doesn't miss a trick. Speaking to Closer Online, Lina said: "I deal with masses of stag and hen dos and I don't want to reveal too much that stops them from coming.
"There's CCTV everywhere, and I don't want them to think I'm going to spill the beans that they were all sh*gging each other in cubicle three. You can see anything at any given time, but as long as they're all having a good time it's fine by me."
As well as looking after the 80-90 staff members she takes on every year for the high season, Lina also has to keep an eye on co-star Suzie White.
Lina continued: "There's always someone who needs something, a lot of it is Suzie and she's 34! I don't know if she's ever going to grow up.
"We got an early flight [to London] this morning and she said, 'Will you ring me when you wake up?' I said, 'No, you have to start standing on your own two feet!'"
A series highlight for former lingerie model Lina was posing for a new shoot – and she hopes it will inspire other women to overcome their body issues.
"I got my kit off and did a lingerie shoot at 54-years-old, but it was quite invigorating.
"I did it for the perimenopausal ladies out there, because I'm perimenopausal. So many people, particularly in Marbella, are very body conscious and I don't get it!
"I think everyone needs to stop worrying about cellulite and wobbly bits and be body confident when they put on a bikini. The shoot was quite a scary thing for me to do, even though I'm quite out there!"
