Blackpool Supporters' Trust chairman Steve Rowland believes fans will face a "real crisis of conscience" as they decide whether to follow the team to Wembley.
Promotion is in sight as the Seasiders prepare for the Sky Bet League Two play-off final at Wembley.
But many supporters will continue their boycott in a protest against chairman Karl Oyston and his family's running of the club.
Gary Bowyer's squad came through a dramatic semi-final second leg against Luton on Thursday night. An own goal from Hatters goalkeeper Stuart Moore in the last minute of stoppage time saw the Tangerines record a 6-5 aggregate win to book a Wembley date against Exeter on May 28.
The Blackpool Supporters' Trust (BST) has established a 'Not A Penny More' campaign, targeting the interests of the club's owners, which includes staying away from home matches at Bloomfield Road. Attendances have plummeted this season as a consequence.
Blackpool were a Premier League side in 2010-11 before dropping down the divisions.
Rowland understands it is a hard decision not to follow the team to Wembley, where protests are planned for outside the stadium.
The BST believes it must look at the "bigger picture" and maintain the drive for a change in ownership.
"The big protest for Blackpool supporters this season has been the ethical boycott," Rowland told Press Association Sport.
"We have been staying away in our thousands, but at the same time letting it be known that we do support the manager and the team, and we wish them well.
"Of course the fact they have now got to Wembley means it is a real crisis of conscience for lots of people, but I won't be going personally and this will be the first play-off final in 25 years that I have not been to - and that comes hard.
"But we have to look at the bigger picture here and the bigger picture is Blackpool is a club that just seven years ago had qualified for the Premier League and had a huge opportunity.
"But all of that good work by the team and the manager at the time, as well as the thousands of fans who supported them, we view as being squandered by the Oystons and the way they have run the club subsequently.
"We would love to support the team, we hope they win, but the majority of us are not going to be there (at Wembley) inside the stadium on the day."
Oyston has been urged by fans to sell up but this week told BBC Radio Lancashire he had received no offers for the club.
"We'll talk to anyone but you can't talk in 'ifs'," Oyston said. "I don't think there's a queue forming at our door, we've still got problems at the club and we've got to address those problems and try and move on. I'm not sure we'll be top of the list for people who want to buy a football club."
Oyston also said he hoped to "repair what can be repaired" in the relationship between the club's owners and the supporter base.
The Trust has, Rowland stressed, always said "it is an individual fan's right to chose whether they go or not".
Rowland added: "The ethical boycott and the 'Not A Penny More' campaign are not compulsory, but we have said there is strength in numbers and the more people who stand firm the clearer that message is.
"If they (fans) want to go (to Wembley), we quite understand that.
"We hope if they do then they will both support the team and also at the same time let it be known that they don't want the Oystons there any more."
Rowland added: "The only real constructive way forward is for a change of ownership - and there are thousands of die-hard fans waiting in the wings to come back once that happens."
