Compact travel cot?

Hi, does anyone know of any nice value travel cots. ive searched eveywhere for an ulta light weight one that either pops up of easily assembled but they are either bulky or expensive. im going to spain and although the hotel provides cots, its going to cost £8 per night, so its works out alot for a 14 night stay! i figured i may as well buy one. if not a travel cot, does anyone have an ingenious idea that they have tried and tested? he will be 17 months.thanks
