Whitbread booked a 20% rise in first-half profits after its opening of new hotel rooms helped boost revenue.
Pre-tax profit rose to £316m, up from £264m, after revenue jumped 7.4%.
Much of the growth in revenue came from the Premier Inn hotels business, for which the company opened more than 2,000 new rooms.
Like-for-like revenue growth at the Costa coffee chain, however, slowed to 0.6%.
Whitbread declared an interim dividend of 31.4p, up 5% on the previous year.
"Despite the well known short-term economic uncertainty, our performance in the first half was good and we expect to meet expectations for the full year," the company said.
