Fax are following the example of last Monday's opponents Dewsbury, who stayed in South Wales over the weekend after their Good Friday date with John Dixon's men.
That meant an early start for Calland's players today, with the team not due to return north until Sunday afternoon.
"We will travel down today and make a full weekend of it," said Calland.
"It will give me time to do the little extra things in preparation for the game that the full time teams are able to do all the time.
"We'll do some one-on-one tutorials, some more video work and things like that.
"It's a great opportunity for us and hopefully it will give us the best chance of coming back with the three points."
One of the biggest factors - literally - tomorrow evening is the Brewery Field playing surface, touted as one of the most expansive in the professional game.
A week ago, it was also one of the muddiest, with the home side outpointing the Rams in truly appalling conditions.
"It's a massive field, about 100 metres long and 75 metres wide with 10 metre in goal areas," said Calland.
"It is probably the biggest field I have seen and Celtic have developed a style that suits it.
"The conditions looked terrible on Good Friday, but hopefully it will have dried out a bit this week.
"Whatever sort of condition it's in, we'll come up with a plan to try and take advantage of it."
Calland was not planning to announce his squad for tomorrow's encounter until later today.
Centre Mike Ratu (concussion), half back Mick Govin (knee) and forward Danny Heaton (knee), all missed Monday's gutsy 36-34 win at Rams Stadium.

HALIFAX have slashed admission prices for their Northern Rail Cup tie against Celtic Crusaders at the Shay on Sunday week (3.0).
Fax officials were encouraged with last Thursday's attendance against Sheffield Eagles, when a 'kid for a quid' promotion contributed to a turnout of 1,654 on a shocking night.
The club have now priced Sunday's game at £10 for adults and £5 for concessions, with free admission to under 16s, representing a considerable saving on the usual £14 adult price.
Fax chief executive Graham Clay said: "There are a lot of very positive things happening at the club, and we believe this could be a special season for us.
"We want as many people as possible to join us down at the Shay and be part of what's happening.
"The team is playing an exciting, fast-flowing type of rugby, the East Stand is going to be completed and we are applying for a Super League licence.
"These are exciting times, and our pricing structure for the Crusaders game makes it a very affordable afternoon out for the whole family."

The demanding Easter schedule will test the stamina of Wakefield, whose coach John Kear was left with just a day to prepare his side for tonight's game at Wigan following their Easter Monday trip to Perpignan.
"While Wigan have gone seven miles to St Helens, we've been to the south of France and back," said Kear.
"That's the contrast.
"It is a tough ask, especially when you've got blokes missing - and the medical staff were denied the chance to deal with the bumps and bruises because we lost two days' travelling.
"We came back Tuesday; yesterday was a rest day and today we're counting the bodies and doing a very light training session."
Danny Brough (dead leg) and Sam Obst (hamstring) are the Wildcats' latest casualties.
