The new contract will include wage increases, affordable health care and decreased workloads for housekeepers.
It also provides job security and seniority protection for both full-time and part-time workers.
The union still has to vote on the contract, but it's expected to pass.
The agreement would put an end to a nearly four-year dispute that led workers to stage a series of protests.
The workers' contract expired in February 2008.
A key sticking point in negotiations was a free health care plan for maids, bell hops, cooks and dishwashers at three Disney-owned hotels that the resort wanted to eliminate.
Disney is the parent company of ABC7.
