Wales have visited Spala and Gdansk in recent years ahead of major tournaments, making use of the cryotherapy facilities available to aid preparations. Those camps were widely credited as an important factor in Wales' 2012 Six Nations Grand Slam and their run to the semi-finals of the 2011 World Cup in New Zealand.
But on this occasion the squad will instead stay at their National Centre of Excellence in the Vale of Glamorgan, although they will still have access to a cryotherapy chamber. "We are staying in the country this time," Howley told the Western Mail.
"We have gone to Poland before on the last two occasions but it is a different environment now and we have chosen to stay at home.
"Hopefully we will have the English and French players available for the three days in that first week of training.
"That would give us the best available preparation with the squad we have got."
Wales head into the defence of their Six Nations title on the back of seven straight defeats, and will be without fly-half Rhys Priestland (Achilles) and lock Luke Charteris (shoulder) for the entire tournament.
But props Adam Jones and Craig Mitchell, centre Jamie Roberts and full-back Leigh Halfpenny have all returned to action after injury.
