Camping can be great fun (when you get used to it). It helps when the climate is just right (18-28 degrees).
Most of the one-person lightweight tents (under 1.5kg) are frankly ridiculous when erect but they will do the job and camping is the best way to keep your costs down (so you can stay away for longer).
My new tent is lovely and (for a claustrophobe) relatively spacious. There’s a whole list of extra stuff you will need to camp but for now I’ll let you just imagine spending a balmy night on the sweet grass.
