This cruise boat on beautiful Lake Winnipesaukee (which is home to 365 islands) offers day, night and dinner cruises with entertainment from spring to fall. It's moderately expensive ($14 & up), yet worth the price if you're in the area. It launches from multiple points and drops off as well. It's base is at Weirs Beach, an interesting section of town with arcades, pizza parlors, a beach, and old homes.
Stop in and see what all the fuss is about. Funspot is a huge entertainment complex located on Route 3 in Weirs Beach, NH. Here you'll find hundreds of videogames including over 200 classic (pre-1987) video & pinball machines. This is the home of the premier classic game contest, drawing players from as far away as Israel each year. It also houses a 20 lane bowling alley, a mini-golf course, a driving range, a bingo hall, and an indoor golf center with state-of-the-art virtual golf and a retro mini-golf. You can get an amazing amount of tokens here for your money (125 tokens for 20 bucks!). Many events are held here including huge annual Halloween & Christmas parties and an incredible fireworks display. Funspot is over 50 years old!
It's impossible to miss... just past the beaches if you're coming from the south, right-hand side. Look for the huge lit signs!
just once in your life, you should go to a bike week. Laconia holds one every July, and bikers from around the World attend. Always a good time even if you don't ride. Spend a week here and you will find out what I have known for years, bikers are some of the best people you will ever meet.
You must take a cruise on the Mt. Washington. It is a huge ship which will take you all over the lake. If you have kids, you must go to Funspot, the worlds second largest collection of antique games! IF it's hot, you must to to Surf Coaster USA or the Weirs Beach water slides, both at big water parks.
These attractions alone would make for a great vacation, but there being placed in such a beautiful spot makes it all the better.
