I just priced April vacation week for us (also in MA) we are a family of 5 and it was $5,600.... not happening! Thats going to be the price of my 11 day trip in Aug with airfare.
Good luck I really feel your pain here.
It's totally nuts! I would normally never go during this time but it was either February vacation or April vacation because we have four school age kids and two school teachers traveling with us so it has to be during a school vacation. I had tried to push for February thinking fares would be cheaper but they ended up being just as expensive this year anyway.
