The Welsh football side will ban players' family and partners from the team hotel during the initial stages of this summer's European championships.
Boss Chris Coleman said the initial ban would cover the team's group games, as they look to make a major impact at their first tournament appearance in 58 years.
The former Swansea City, Fulham and Crystal Palace defender said: "We have three games and there will be no family, no girlfriends, no wives in our hotel in the first period of the group stage.
"We have three games in 10 days and there's no time, we are preparing, travelling, playing, travelling.
"We said, let's get through the group, because then there's a six-day period and we can have a day where we say it's OK to spend some time with the family - and then, bang, we are at it again."
The Welsh squad will be based in the Brittany coastal resort of Dinard during the tournament, which begins in June.
The ban includes the Sky Sports presenter Charlotte Coleman, who is married to the manager, and Emma Rhys-Jones, who dates talisman Gareth Bale.
Wales will face England, Russia and Slovakia in the group stages of the competition.
Coleman, 45, said: "We are out there to make sure we do Wales proud and to do that we have to prepare properly."
