Businesses have had a mixed start to the summer season, according to South West Tourism's latest survey, with some saying trade is down on 2003.
The report, which covers April to June 2004, shows a third of tourism companies are showing a "decrease in levels of activity" in this quarter.
But 39% of those polled said that turnover was up compared to 2003.
Just over 60% of business leaders are complaining that increased costs are becoming a problem.
'Tough year'
The South West Tourism survey acknowledges that 2003 was an "exceptional" year and that comparisons with 2004 make this year look "average".
Robin Barker, deputy chief executive, said: "The report shows that 2004 has been a tough year in some parts of the region.
"It's been a generally good start across the whole South West but has been a poor spring and early summer in parts of Devon and Cornwall."
