Is the single room big enough for 2 people

Yes

Yes, & honestly my family of 3 (my wife, our 3 year old son & myself are actually very comfortable in a single room. ALL rooms haven't been long ago, completely remodeled, new paint job on the inside of each room, nicer furniture, a helluva lot better beds, flat screen tvs in every room. Nice bedding/linens & pillows & towels, bathrooms are clean & supplied with toilet paper, 2 bars of soap, nicer, newer towels, rags, & a hand towel & of course toilet, sink, & nice shower. Lighting is alot better through out the whole room. Great working air conditioner in the summer & awesome heat in the winter. Room is also equipped with a tabel & at least 2 sturdy sitting chairs. A nice 4 drawer dresser, good cold working mini fridge & nicer microwaves. Has at least one night stand & phone you can call out locally on, & from what I've seen in all the different rooms they have a Bible included. Vehicle parks in front of your door. Fenced in clean pools, sm kiddie & the adult pool! I have photos also
