Ive stayed in tents at eurocamp and canvas and it was good, you could stand up in them tents and walk around and the cooking equipment is inside as well. Ive just returned from camping near newquay and it was good. Id suggest you buy a tent you are happy with, try and go to some retailers who have tents pitched up, i would get a tent from tesco or argos as it may not last long, a lamp/lantern, a way to cook food eg gas stove or a similar device, id also reccomend some camping pots and cutlery.
