I live in Clifton Park, which is about 30 minutes from downtown Saratoga. Saratoga is a beautiful place and, if we have nice weather, I would highly recommend just walking around downtown, visiting the park, all the shops, etc.. Loads of restaurants and pubs. Pick one - I don't think you can go wrong. Limoncello's is great.
There is the Racing Museum (Saratoga Racetrack is right there, ya know! - Very popular place in August!) also there is the Dance Museum, which I believe, John Travolta was just inducted into for "Saturday Night Fever".
There is a great spa (Aveda Spa) right on the downtown strip if you are into that. Great Facials!!! And they sell Essie nailpolishes (which I love!)
Saratoga runs from Northway Exits 12 (south end) to Exit 15. Up around Exit 15 is the Wilton Mall (although I haven't been there in ages so I can't say how it is). We have the Clifton Commons Mall here at Exit 9 (which is about 25-30 minutes from Saratoga). There are lots of new shops in there and a spa as well.
Crossgates Mall in Albany is at the complete other end of the Northway. It has it's own exit - it's huge. Albany also has a great museum. There may be a show at The Egg http://www.theegg.org/events
- check for when you're coming and perhaps take in a show. For additional shows there is also The Palace Theater
In Schenectady, which is the city I work in, we have Proctor's Theater http://www.proctors.org/
, which is a beautiful, newly remodeled theater. There is also a nice yarn store on Union Street (right up the street from my office - DANGEROUS!) called Ye Olde Yarn Shoppe.
Anywho, lots of stuff in this area. You probably won't be bored. I hope the weather gets better for your trip. It's in the 50s and rainy lately. All the trees are budding and beautiful, but it's much prettier in the sun. Have a great trip and consider this area. I've lived here my whole life and love it. (I sound like a travel brochure..."Come to Jamaica"....HA!)
