Ten tour groups have already booked in at Hennessey's Irish Bar and operations manager Sue Burnett expects they'll be run off their feet the entire tour.
"Last time [2005 Lions tour] it was legendary. They picked a number of venues throughout the country and they had a wonderful time here.
"We will be getting a lot of repeat customers because we looked after them so well."
Rotorua Top 10 Holiday Park owner Jared Adams said as expected, all rooms that weekend were just about booked.
They had just 20 out of 65 powered sites still available at this stage.
"I have no question, especially being in the city centre, we will get booked out and pretty quickly.
"I worked at a bar the last time they came. It was such an amazing environment. They're such a happy bunch of people."
Eat Streat businesses were still concentrating on the summer season but "100 per cent the tour will be on our radar soon", said Eat Streat Collective spokesman Tamati Coffey.
"It will be a great opportunity to show Rotorua and Eat Streat off to the world. We know what busy looks like and this is going to be huge."
Rotorua Association of Motels chairman Mike Gallagher said motel bookings would start coming in hard and fast from now until the month before the event.
He expects this year's Lions match in Rotorua will "go off" and there may be an overflow of visitors to the area looking for accommodation.
Rotorua Lakes Council operations and event development manager Crispian Stewart said the programme of events scheduled for Rotorua during the series was still being confirmed.
"It is expected that there will be a series of lead-up rugby games and other rugby-related activities with local clubs. The Maori All Blacks will be arriving the Sunday before the game (June 17) so there will be opportunities for fans to meet and engage with the team.
"We know it will be a very exciting time for the community. We want to encourage Rotorua to get behind the game which is considered the unofficial 'fourth test' of the series."
