I'm not sure what to say that hasn't already been said in the other reviews - but I can say I highly recommend Forgotten Seasons.
The B&B is a charming, historic building (where the founding of the Moravian Community at Lititz began) that was once an inn. It's comfortable, spacious, clean and nicely furnished. There two sitting rooms, a "library" room with filled with local history books, photos and documents, a large dining room where breakfast is served and two big porches with chairs. There are 3 large guest rooms, two of which have en suite facilities.
Coffee and tea making facilities are located in one sitting room (available 24 hours) and fresh baked cookies were put out just after I arrived in late afternoon.
I stayed in the Count's Room, which had a king-sized four-poster canopy bed with traditional quilt, a big wing chair and a rocking chair, and a nice, peaceful atmosphere. My bath was across the hall (not shared), but I'm used to that in British B&B's, so I didn't mind. I liked that it faced the back of the house, away from the road.
The location is just far enough out of town to be peaceful but only 5 minutes drive to the center of Lititz, or about 20 minutes walk via a "linear park" that passes right by the B&B. Parking is plentiful.
The hosts, Jay and Kathy show endless hospitality towards their guests. They are friendly, accommodating and very knowledgeable. Kathy gave me an informative tour of the house when I arrived and both she and Jay were happy to talk about their work on the building and their lives in Lititz.
They also provided a copy of a circular driving tour they devised, which starts and ends at the B&B. It takes you through 5 covered bridges and miles of beautiful Amish farmland - the kind of scenery you don't see along the congested Route 30 corridor closer to Lancaster itself. I enjoyed it that immensely and saw dozens of horse and buggies and Amish families along the way.
Then there is the breakfast, which was fantastic. I don't know if breakfast is always that lavish, or if it's more of a weekend treat but it couldn't have been better. The day I was there we had Kathy's homemade rhubarb-pineapple juice, toasted homemade bread with jam and apple butter, fruit salad, an egg dish served with pork roll, and then giant waffles with fresh peaches. Many of the ingredients, including the fruit and eggs are fresh from their garden and farm. It's served family style in the tavern/dining room and lent itself to friendly conversation among the hosts and guests. You won't find a breakfast like this at any hotel!
Not only is the B&B close to the town of Lititz, but it's only a few miles to the PA Wolf Sanctuary at Speedwell and the Ephrata Cloister, both of which I enjoyed visiting. I would say this is a good location for any visit to the Lancaster area, not just the immediately local attractions.
Note that this is a peaceful place - good for conversation, reading, relaxing (and eating!) - there is no TV, radio or Wi-Fi, so if you can't live without that for a few days, it's not the place for you or your rambunctious children.
I was lucky to find a room on short notice, but you need to book quite far in advance when any of the big events in Lititz are being held.
