Tom, I just called Comcast, I was first connected to Connecticut, then transferred to MA and finally got FL, but that is another story

. You are right about the 7/15 date. I have never left FL this late, so I was unaware the ability to put your Comcast account on vacation for the summer ends 7/15.
We do not have phone via Comcast, we use Verizon wireless and Skype for phone. My summary information I learned below does not include costs for phone vacation or hookup.
For Comcast we have television (tv) (extended whatever), HD and DVR, and high speed internet.
If we put the
whole bundle on vacation Friday there is a one time fee of $80 (no hookup fee, no returning boxes).
In the three previous years, we have done something like
bob45, canceling everything except BASIC tv and putting just
BASIC tv on vacation. If we do that it is a one time fee of fee of $20. (no hookup fee, must return boxes)
If we
cancel the whole thing we return boxes and pay a hookup fee of $40.
Tom, sounds like the last one is your only option. As
bob45 said it may work because Comcast has no contracts, so you are eligible for any deal a new customer gets upon return. Doing it the way we have done (downgrading service to basic cable and putting that on vacation), we have gotten some deal every year upon return and upgrading our service. Every year, when we return we look for specials and always get Internet for $19.95 for 6 months and some years get other stuff.
Anyway... now I have to think what I am going to do.....
