OCA Annual Conventions

OCA's version of a serious winter thaw, the Annual Convention draws members to high-profile destinations around the world. Members recharge with just the right blend of industry-relevant speakers and education programs, rich networking and relationship building opportunities, local history, entertainment and...FUN!

In 2020, the group relaxed on the island of Maui. In 2022, it was Aruba. In 2023 it's Barcelona, Spain!

The five-star resort was designed so that guests can easily explore the island or never leave the hotel grounds.
