We pass through here twice each summer and have found the Country Inn & Suites to be our best option. Nothing fancy, but always (in our experience) consistent -- that is how we think of Country Inn & Suites generally, and certainly of the Hagerstown location where we have now stayed three times.
Thankfully, this place has not been overrun by swarms of teenagers on weekend soccer/basketball/cheerleading/etc camps/tournaments -- the type of thing that leads to noise all night long, never-ending waits for elevators, etc and which seem to happen very frequently at these interstate-side stopovers in smaller towns. This hotel however seems mostly to be younger families and quieter types (maybe the slight bump up in price for the suites-style room discourages the sports teams, I dunno). This type of clientele (and avoiding the other) helps a lot if you want to get, you know, SLEEP.
These places aren't fancy, but they do one thing quite well: their definition of a 'suite' means a working door that closes off the bedroom from the rest of the room. Not every hotel chain does it this way -- some just use strategically placed furniture, others use half walls, etc. The working door is a meaningful differentiator in our book, as our two kids go to bed around 8pm and generally we like to have a little time awake to ourselves after that.
The breakfast is pretty decent for a 3* hotel, the pool is okay (nothing great). Our experience with the rooms (cleanliness, amenties, general condition) has always been at least passable and in fact positive.
We've stayed in the Spring Hill Suites in Hagerstown as well, and generally find the Country Inn & Suites to be better all around.
We ponied up for one of the large suites this time and found it to be an even better fit for our needs: tons of space in the common area, so our kids could be separated by about 15 feet when it was bed time (a lot less risk of them keeping one another up, simply because they couldn't see each other this time). Entrances to the bathroom from both the bedroom *and* from the common area -- this was great because we could use the bathroom in the night without passing through the common room and risking waking up the kids. The jacuzzi was very large: an adult and two young kids could all be in there together simultaneously with relative comfort.. The room was $214 +taxes, which is steep for a 3* hotel in a small town ... but given those amenities we were glad we did it. It just fit our circumstances very well.
They claim to benefit from the nearby mall security, but I would recommend not leaving valuables in your car. This isn't exactly a crime-ridden 'hood, but there were two spots in the lot where window glass was an obvious marker of break-ins. Probably just knucklehead kids coming over from the mall -- this is not an unsafe place at all, just one where you would do well to park under a street light.
As other posters have mentioned, this hotel does have the benefit of many eating choices due to its proximity to the mall. There is a decent selection of fast food spots, to be sure. Parents, you should know that when you drive up to the hotel directly across the parking lot and in fully view about 50 yards away is Chuck-E Cheese ... so invariably you have to be ready to deflect a cascade of 'puhhhh-leeeeeezes' that might be tough if you've had a long day of driving. :-)
