Most Cardiff hotels make you fight a busy lobby to load a band in. Holland House does not. There are dedicated loading doors on the street that runs behind the hotel, and they open into the back of the Calon Suite - so a full showband’s worth of flight cases comes off the pavement and straight into the room the party is happening in, rather than threading through reception at check-in. It is the sort of detail that means nothing until you have humped a bass rig the wrong way through a hotel foyer, and once you know it, Holland House is one of the easier big rooms in the city for The Brotherhood to get into and set up.

The Calon Suite, and the Caernarfon for smaller nights
Holland House is the big four-star on Newport Road, a ten-minute walk east of the castle and lately rebranded from Mercure to “by Sunday”. For corporate work the room that matters is the Calon Suite: a large ballroom that seats around 450 for a banquet or cabaret, with its own private entrance, bar, kitchen and a built-in stage. That is a proper awards-dinner and conference-gala room - the scale where Cardiff’s bigger companies put their annual do. It also divides, so a smaller event does not have to rattle around the whole space; we have played plenty of nights in just part of the Calon with the rest partitioned off. For genuinely smaller functions the hotel also runs the Caernarfon Suite - not to be confused with Celtic Manor’s - which takes about 140 for a banquet or 128 cabaret and comes with its own bar and a lot of natural light.
Loading in, and who brings the PA
The back-of-house access is the headline. Those loading doors behind the hotel drop you into the rear of the Calon Suite, and from there it is a short push to wherever the performance area is set for the night. We usually park on the streets around the back - pay and display, and not the extortionate city-centre rate you brace yourself for.
The other thing worth knowing is who supplies the sound. The Calon has a stage and house AV for presentations - projector, screens, conference audio - but it is not a full-production live-music room like DEPOT or ICC Wales, so more often than not we bring the whole PA ourselves and run the room front to back. That suits us: our own rig, our own engineer, tuned to the room on the day. Where a client has booked a separate AV or production company for the conference side, we have worked alongside them plenty - we take a feed or hand them one, agree who owns front-of-house, and keep the band’s footprint out of their way. Either model works here; it is just a conversation to have early so nobody turns up assuming the other party brought the speakers. We run in-ear monitors, so there are no wedges on the stage, and guitar and bass go straight to the desk rather than through amps - the stage stays tidy and the only sound in the room is what the front-of-house PA puts out.
Sizing the band to the Calon
The Calon at full stretch is a 450-cover ballroom, and a room that size and shape carries a big lineup comfortably - this is where an eight or nine-piece with horns earns its place, filling a wide ballroom with brass and a full rhythm section rather than leaning on volume to reach the back tables. When the suite is partitioned down for a smaller dinner, or the night is in the Caernarfon, we scale accordingly - a tighter six or seven-piece with keys sits better in a half-room than a full horn wall would. Tell us the guest count and which configuration the hotel is setting, and we will steer you to the size that suits the room on the night rather than overselling brass into a space that does not want it.
How a corporate night runs here
The Calon’s private entrance and bar mean the evening can live entirely in one wing of the hotel - arrival drinks in the bar or pre-function space, guests through for dinner and any awards or speeches, then the floor opens up. We load in and line-check before doors so the stage is set and quiet in the corner while the formalities run. After dinner we play two sets of around an hour, blended together in our own style and stacked with floor-fillers, with a DJ or playlist covering the gaps and carrying on after us to the end of the night. An awards evening puts the band on once the trophies are done; a Christmas party wants the floor up the moment the plates are cleared. We take the running order in advance and work it back from whatever time the room has to be out, so the band, the dinner service and the speeches slot together instead of colliding.
The Brotherhood are a Cardiff corporate band twenty minutes from our Newport base, and Holland House is home turf on the Newport Road. Check our availability for an awards dinner, conference gala or Christmas party in the Calon Suite, or see how we work the wider Cardiff corporate circuit.
