Barack Obama and John McCain couldn`t have planned more different election night parties if they tried.

A million people are expected to crowd into Chicago`s downtown Grant Park Tuesday night where the lucky 65,000 Obama supporters able to get tickets to the party will be able to buy hot dogs and hot chocolate from concession stands.

Canapes and cocktails will be offered to the few thousand McCain supporters expected to come hear the Republican presidential hopeful speak on the lavish grounds of the Biltmore Hotel in Phoenix, Arizona.

`It`s a beautiful setting with the mountains behind,` said spokeswoman Kimmie Lipscomb. `It will be a very stunning setting for John McCain to conclude his campaign.`

A ballroom with live music and a video feed to McCain`s speech will be set up as an overflow venue for those who can`t be accommodated in front of the stage on the resort`s lawn.

The Democratic frontrunner`s campaign has still not said whether screens will be set up for the hordes of people expected to flood into the sprawling lakefront park.

Local media have been peppering city officials to make sure enough portable toilets and security will be set up and publishing guides for residents on what to expect.

The city`s mayor has vowed to accommodate anyone else who feels like joining in the celebration, saying the parkland and sidewalk areas outside the fenced-in baseball field are `big enough to handle a lot of people.`

`You cannot make it just an exclusive party for a few,` Daley told reporters last week.

`Senator Obama`s campaign has never been about a few. It`s been about many people so that`s what we`re trying to do. You cannot say you cannot come down.`

Downtown businesses have been asked to send their workers home at 3:00 pm to help clear the way for the throngs of supporters, street parking will be banned in the downtown `Loop` area, and hundreds of extra buses and trains will run.

The harbor patrol will be out to police the lakefront, every cop in the city is on call and firefighters have been asked to bring their gear home with them to shorten response times.

Police superintendent Jody Weis said he was `extraordinarily confident` that everyone will be kept safe but warned people to behave themselves.

`We can`t have foolishness. We can`t have mischief,` he told reporters.

Unseasonably good weather is forecasted for the windy city on Tuesday, which could increase the number of people willing to wait outside for the election results to come in.

While Obama is significantly ahead of McCain in the polls, he is not expected to speak before 11:00 pm local time (0500 GMT.)
