PORTLAND, Maine — Gay couples are booking wedding dates and exchanging vows in Maine, but inns and wedding venues aren’t expecting a deluge of new business like Massachusetts experienced when it became the first state to legalize same-sex marriage nearly a decade ago.
About 2,360 same-sex couples were married in Massachusetts the first month alone after its gay marriage law went into effect in 2004, according to the Boston-based Gay & Lesbian Advocates & Defenders organization.
In contrast, about 150 gay couples have exchanged vows in Maine since same-sex marriage became legal Dec. 29. While the new law has given hotels, photographers, florists, and others a boost, many say they’re not anticipating a bonanza from same-sex couples right off the bat, but still expect the gay marriage business to grow in the years ahead.
The Portland Regency Hotel has booked three same-sex weddings for this year. Besides making money from the weddings, the hotel benefits because wedding parties often book blocks of rooms for guests, said David Davis, director of sales. The hotel has also gotten room reservations for same-sex weddings that are being held elsewhere.
Gay weddings represent a sliver of the hotel’s events business, he said, but he expects it to grow over time.
‘‘We’ll see more bookings in 2014 and 2015 and beyond,’’ he said.
When Massachusetts legalized gay marriage, there was a rush to get married because it was the first state to allow gay marriage and there was uncertainty whether the law would survive, said Lee Swislow, executive director of Gay & Lesbian Advocates & Defenders.
‘‘Maine is in a much different position than Massachusetts in 2004,’’ Swislow said. ‘‘If you wanted to get married then, this was it.’’
Now, in addition to Massachusetts, gay marriage is legal in neighboring New Hampshire, six other states, and the District of Columbia.
As of Feb. 25, the Department of Health and Human Services had recorded 148 same-sex marriages in Maine, 78 of which took place the first three days the law was in effect.
