(CNN) – While Mitt Romney said he expects his fundraising calendar to be "a little quieter," a senior campaign adviser sounded less certain Monday about taking donor meetings off the Republican nominee's itinerary in the near future.
"We're going to reach a point here–hopefully soon–where we'll have the resources we need to carry us through Nov. 6 and we don't need to be doing those finance events," Ed Gillespie said on a conference call with reporters.

Some conservatives have criticized Romney's campaign for spending too much time on the fund-raising circuit, rather than holding campaign events in crucial swing states.
The former Massachusetts governor, for example, spent much of last week raising money in California, Utah and Texas–states not considered up for grabs this fall. It's worth noting, however, he stopped in the battleground states of Florida and Colorado, as well.
Romney told reporters on a plane Sunday night his campaign has been "heavy" on raising money, but he also laid out an expected change in pace. "I think the fundraising season is probably a little quieter going forward."
Gillespie, a former Republican National Committee chairman, also acknowledged Romney had been doing "a lot" of fund-raising events and argued the White House hopeful has to keep up with President Barack Obama, who opted out of taking public finance campaign funds in his 2008 and 2012 presidential bids.
Last month Obama's campaign surprised political analysts by hauling in more money than Romney.
"Obviously we have to compete with a very well-funded Obama machine on the other side," Gillespie said.
Romney holds a public event Monday in Colorado before heading to New York City to speak at the Global Clinton Initiative. Also on the trail, his running mate, Rep. Paul Ryan, kicks off a three-day bus tour in Ohio, which Romney will join on Tuesday in Dayton.
The Romney adviser said he's optimistic the campaign will be able to spend longer stretches in "target states" and focus on "political events" as opposed to fund-raisers.
"We're all looking forward to that moment in time," Gillespie added.
