Depends on what ya'll are interested in seeing and doing while on vacation...
Within the city itself there is Old Town, and there are a few museums in the same vicinity (Natural History, Art, and Childrens), the Zoo, and The Botanical Gardens (collectively known as the BioPark).
There might still be a museum on the air force base (Kirtland) where you can learn about fat Man and Little Boy (the bombs dropped on Hiroshima in WWII) and miltary history, but that may not still be around- I know they closed briefly and then restricted access after the Sept 11th attacks so not sure what its status is currently, and I no longer live there so maybe someone else can chime in...
On the West side there is Petroglyph Park but again maybe someone else can chime in with more info as I know in the past there have been problems protecting the glyphs from punks with scrapers and spray paint
...
On the east you will find the Sandia Mountains and the tram to the Peak. There are several scenic hikes and picnic areas, and the tram ride is fun with a gorgeous view all around.
If you golf, there are many courses to choose to play. If you find yourself in the mountains headin for the back side (headin east of the city) there is a beautiful course called Paa Ko Ridge. It is challenging but the place is so so pretty. It is unfortunately a bit expensive, but if golf is something you all enjoy- go for it!
About 30 minutes to the North you will find Santa Fe and Taos- lots of art museums and galleries, and your typical outlet mall. There are also several different Pueblo's/Reservations that offer tours and education on handcrafts in the area (and there are also a growing number of Indian casinos as well).
Hope that helps a bit!
