Conference Park 25/7 is a congress and meeting complex in Opatija, on the Kvarner coast of Croatia, with nine multipurpose halls on 1,500 square meters and a total capacity of 1,000 people. It belongs to the Amadria Park group and stands at Viktora Cara Emina 6. The largest hall combination takes 450 people.
Seminars and company events
All halls are column-free, which keeps sightlines clear for plenaries and keeps layouts flexible. The nine single halls are 0A, 0B, 1A, 1B, 1C, 2A, 2B, 2C and 2D, and neighboring halls combine into larger rooms. A conference for 400 can use 2ABCD, and 1ABC reaches 450. Smaller workshops fit the 32 square meter halls on the second floor, each rated for 40 people.
The venue describes three ways to use the space: Sea Office, Out of Office and Market, the last of which also works as a startup incubator. Stage areas, self-serve coffee bars, lounges for informal networking and on-site registration areas support the program, and AV support is available quickly. Terraces with sea views, promenades, parks and pool decks are close by for breaks.
Rooms and capacities
Capacities rise in steps. Hall 0B holds 22 people on 30 square meters. The 32 square meter halls 2B, 2C and 2D hold 40 each. Halls 1B and 1C hold 75, and 2BC holds 80. Combination 2BCD holds 120 on 100 square meters, 1BC and 0A hold 150, 2A holds 220 and 1A holds 250. Hall 0AB holds 300 and an open-plan setup on the ground floor also holds 300. The site does not say which layout each figure refers to, so ask for the capacity in theatre, banquet or classroom style.
Accommodation
Delegates stay in hotels in Opatija. The venue lists six hotels of the Amadria Park group in town, so rooms can be arranged close to the conference center.
Catering
The site mentions quality catering on site. It publishes no menus or packages, so request the food and beverage options with your date.
History and setting
Amadria Park describes the complex as a town on a small scale: halls, lounges, coffee bars, a market format and terraces in one place. Opatija is a resort town on the Kvarner coast, with sea-view promenades and parks next to the halls. Participants can move between registration areas, plenary halls and outdoor spaces without leaving the complex, and the same group runs the hotels where delegates stay, so meeting space and rooms can be requested together.
Getting there
The address is Viktora Cara Emina 6, 51410 Opatija. The closest airport is Rijeka, 19 kilometers away. On-site parking is available.
