Semi-Formal: Tuxes and gowns/saris are welcome, and so are suits and cocktail dresses/lenghas/churidars.
There is a pre-cocktail space available at Jericho Terrace for guests interested in passing the time between the ceremony and reception.
Consider La Quinta Inn in Garden City that will include a free shuttle to/from Jericho Terrace (see 'Travel' tab), AirBNB or one of the many hotels in the area.
