It has been two weeks since you received your second dose/booster for adults. All children over the age of 5 must be fully vaccinated (2 weeks after the second dose) in keeping with NY guidelines by the time of the event.
The M/R Steinway stop and the 36th Avenue stop on the N are the closest subway stops to the museum.
If you're interested in staying close to the wedding places, there are multiple hotels around Queensboro Plaza in Long Island City (LIC). If you're more interested in staying in the city, feel free to look into any hotel you prefer. Staying on the east side of the city will be a shorter train/cab ride to the wedding venue, but there are good options depending on what you most want to see in the city. We hope you come and explore NYC as well as Queens while you're here.
