I'd be willing to bet this list differs depending on where your vacation home is located and what season is your high season, but here's the question:

What are your recommendations best bang-for-the-buck add on amenities?
Not major structural things like a garage or a mutli-story deck, but simple add-ons that can be purchased for most any vacation home. 

What are the add-ons that people most often ask for, or most often comment on in your guest book?

• Examples: Pool table, big screen tv, dvd library, hot tub, washer / dryer, high chair, fire pit, etc.

Here in the Poconos,we have 2 high seasons: summer waterpark and winter ski.  Most of our visitors stay less than 6 days, often just for the weekend.

Our top requests and/or positive comment getters are:

Everyone asks for:

• Fire Pit.  We refuse to put one in because it's just too wooded in our area and fire from embers is a serious risk.  But everyone thinks it's would be super-awesome to have one.

• Pool table.  We don't have room for one yet, but hope to be able to add one in the next few months.  It's a big request particularly in winter months.  We do have air hockey and fooseball at both houses, which in reality goes over better since more women like air hockey than pool.

• High chair.  We do provide one, and it is a huge draw for families with little ones since they don't have to being their own.

• Hot Tub. We put a basic 4 or 5 person system in at both houses because it is a big differentiator.  Both are just 4 or 5 jets and a single motor - guests don't need or appreciate a bazillion jets - they just want a hot tub to hang out in together.  They're a pain to maintain though, so the investment is far more than just buying and installing it!

• Grill.  We have mid-sized gas grills at both houses.  We suply the propane, with a spare tank available at all times.  So far no one has abused it!

No one asks for but everyone loves:

• A used PS2 console with 5 or 10 SingStar karaoke games.  HUGE hit for all ages.  And total investment under $100 at Gamestop!
  
  
• DVD Library with player - mostly 2-10 year old titles I picked up in the $3 bin at Walmart.  Great for rainy days and late nights.
  
  
• Games, especially games like Don't Break the Ice,  Chutes and Ladders - plus more adult games like Risk and Monopoly.  The games get used nearly every other weekend.  Also - a couple packs of cards - anyone can play solitaire for a while.  We've picked these up at Goodwill and yard sales - and keep a few spares to pirate pieces from as those little green houses have a tendency to get lost!
  
  
• Books, especially children's books - Nancy Drew series, Clifford the Big Red Dog, Winnie the Pooh - plus some fun ones for grown ups like a current copy of Guiness Book of World Records and Do Fish Drink Water?  I stop at the local Salvation Army or Goodwill every so often to see if there's anything interesting on the 25 cent pile.

How about you all - what do your guests ask for, and what are the surprisingly popular amenities that impress your guests?
