In the last five years, there has been a sharp uptick in the number of Kentucky Derby spectators. Getty

While Millionaire's Row and The Mansion attract some of the wealthiest attendees at Churchill Downs, there are still ways to get into the 2017 Kentucky Derby without dropping a huge sum on tickets.

According to online ticket retailer StubHub, general admission tickets run as low as $84 and as high as $209 for the 143rd Run for the Roses.

The drawback to general admission tickets is the large crowd of spectators it attracts. There could be as many as 70,000 attendees in the infield this year.

Seats are still available for every section. Tickets for the lower grandstand are as low as $240. Meanwhile, the average cost to attend the Kentucky Derby is $432, according to VividSeats.

Procrastinators should be cautious. Tickets prices increase closer to the May 6 race.

This year's race may not draw as big a crowd as previous years. There was increased attention on the 2016 Kentucky Derby after American Pharoah captured the Triple Crown in 2015, with ticket prices increasing 2.5 percent. There is no clear-cut favorite in 2017.

There also might be a smaller crowd due to rain in the Saturday forecast.

But wet weather doesn't necessarily mean a low turnout. There was rain in Louisville in 2012 and 2014, but both years drew large crowds to Churchill Downs.

The Kentucky Derby has been a hot event in recent years. In 2015, the Derby drew a record crowd of 170,513, breaking the 165,307 that were in attendance in 2012. Last year, the Derby drew the second-largest crowd, at 167,227.
