Europe leads USA as the record fourth day of the tournament begins The 2010 Ryder Cup begins a fourth day for the first time in its history after rain caused more play delays on Sunday.
It is the first time in 83 years that the tournament, played every two years, has ended on Monday.
Spectators with Sunday tickets are being allowed back into Celtic Manor near Newport, but some fans have already had to travel home.
People with Friday tickets may be able to exchange them for free entry to the Wales Open next June, organisers say.
Russell Phillips, vice-president of the Celtic Manor resort, said the venue was restricting access to Sunday tickets on safety grounds on Monday as it was not known how many would turn up if Friday ticket holders were allowed in as well.
He told BBC Wales: “Then we would get slaughtered if we suddenly had to shut the gates halfway through the day because there were too many people in the course and it’s getting dangerous.”
He confirmed that organisers were hoping to offer an alternative to Friday ticket holders.
He said: “We’re hoping we can do something around (the) Wales Open, where people will be able to exchange their tickets to get into (the) Wales Open.”
Europe lead the US by three points as the fourth day of play gets under way.

One, Constant Priondolo, from Quebec, Canada, said he would loved to have come back on Monday
“I would love to but I’ve got to go back to work.
“Unfortunately, I’m probably going to miss the matches.”
But another supporter, Alan Gordon from Scotland, said he would be staying for the conclusion and he thought a lot of other fans would too.
“I think there will still be a good support, a good atmosphere for the European team.
“The earlier it is the less chance there is of bad weather but money talks in golf”

“Obviously you can get back to Scotland. but getting back to the States is obviously a different kettle of fish,” he added.
Sir Terry Matthews, the billionaire businessman and owner of the Celtic Manor resort, said everyone involved was “deeply disappointed by the weather”.
A total of 52.2mm (2.04 ins) of rain fell at Celtic Manor between 1730 BST on Thursday and 1000 on Sunday, more than half the average monthly rainfall.
But he defended the timing of the event, which has been moved from September to October:
“We could have played this event exactly one year ago or exactly one week ago and we would have experienced no interruptions to the schedule of play, but one thing we cannot control is the weather.
Former First Minister Rhodri Morgan said Celtic Manor deserved to be remembered fondly by the golf fans as its “natural vantage points” allowed spectators to see what golf was being played.
He said: “The Americans did insist on moving [the tournament] forward one week in to October and the risk is always increased.”
“The earlier it is the less chance there is of bad weather but money talks in golf.
“They were warned the longer you leave it, the less sunlight that you’ve got, the less daylight you’ve got to play around with the times. And they decided to take that chance.”
