Since I'm not a Dish rep or retailer, I don't even try and keep up with different packages, promotions, and terms & conditions. However, some possible options that you might want to look into are:
1. Maybe another family member has a dish account that could establish a vacation account at your location. I've heard that Dish was cooperative on stopping and starting service for vacation homes. You may have to own the equipment. I don't know if both locations would need the same programming or not, or if each is treated as a separate account.
2. Buy your equipment and start a new account on a month to month basis. Then stop it when you are finish. Restart it again when ready, and I believe it will be a $25 charge.
3. Sadoun is advertising some month to month units that you use a prepaid card for. I believe it works on regular programming, PPV, and Adult channels, but I don't see why it wouldn't work for sports packages.
