Shane Williams and Phil Vickery played in four tours between them
They then have a further five warm-up games before the first Test against New Zealand on 24 June.
Williams and Vickery aren’t short of experience when it comes to discussing the Lions. England legend Vickery donned the famous red jersey in 2001 and 2009.
Williams toured in 2005 and 2013 – with the latter under the stewardship of current head coach Warren Gatland.
And the former Wales winger insists team spirit can carry the Lions to a historic tour win over New Zealand.
“It's not hard to get along – you don't have a massive hatred,” Williams said.

“When you play against each other [in the Six Nations] they're your arch enemy, but you still have respect for them. It's as important to get on with players off the field as it is on the training ground.
“Warren Gatland is very much a people person. He enjoys guys socialising and going out for a beer if they want to.
“Go out for food, enjoy yourself. Have a few beers, but make sure you turn up in the morning and train hard.
“I might be old fashioned, but I get to know players a lot better over drinks and food.

“That's another romantic side about the Lions. It's not all yes Sir, no Sir, three bags full. It's an old-school tour.

“You all want to win but you also want to have the best time of your life.”
However, Vickery has warned Lions tours aren’t all fun and games.
He reckons having the right character is crucial.
The prop’s debut tour in 2001 to Australia was marred by friction between players and head coach Graham Henry.
Tensions were also heightened following controversial newspaper columns from England stars Matt Dawson and Austin Healey.
“It's about who you are,” Vickery said. "I remember the tour in 2001, there was a big thing with Graham Henry.
“I didn't even know there was a problem. I was happy. The bloke [Henry] spoke to me, he said hello, I knew what I had to do.
“Then all the things came out with Austin Healey and Matt Dawson – but no one likes them anyway.”
Vickery’s second and final tour in 2009 was equally eventful.
South Africa secured victory in the second Test after Morne Steyn kicked a penalty from his own half following a Ronan O'Gara foul.
And Vickery says it can be a lonely experience if the tour isn’t going to plan.
He added: “It's not for everybody. For guys who don't perform, well, you can be like a leper.
“Ronan O Gara [in 2009] in the second Test… We were sharing together! It was like a morgue in our room.
“There's always people you warm to or get on better with, but you're all there for a common purpose.
“You want to win and you do whatever it takes.”
