A good temporary alternative. Accommodating 2 grandsons (10 + 12) who were delighted to be given sleeping bags and saw it as a brilliant adventure. We had long since disposed of our bunkbeds. But if the granpop half is a handyman, bunkbeds are an easy construction and a much cheaper option. Just buy a couple of matresses. I also see on 'Freegle' or the like, used bunkbeds on offer for a song, or free! I dont contribute much, now since the loss of the other half of Geeljay (died suddenly last February). Hope you don't mind the occasional input of a granpop, but my Gillie was a frequent user on Gransnet, I pop in now and again to pass the time. I suppose it depends how often you will have the pleasure of dgs' staying over. Regards to you all
