He said “We are looking at the squad, the preparation for pre-season and where we are going.
“We are also looking at what games we can get and how we are going to work.
“Like last year, we are looking to find a training camp abroad.
“I would go back to Hungary and it is probably our No.1 choice but we are just looking at all our options.
“We might have some games if we go somewhere else so that’s a possibility for us.
“We are speaking to some people just now.”
Hartley also spoke about his side’s recent prolonged break before their next game against Aberdeen a week on Monday.
He added: “It is difficult because your preparation totally changes.
“In a normal working week, you end up with a game on the Saturday.
“But he haven’t had that and it has been hard.
“We just have to keep the players motivated and try to find a balance with how we train, how hard we work and what rest they require.
“We just have to prepare for the Aberdeen game a week on Monday.”
