I will be going on my tour in mid July to end of August. I am doing Summer Fun & Sailing (23 July) which is a hostel type tour and requires a sleeping bag [this is what i read on Topdeck website]. Do i really need a sleeping bag, or can I just bring a sleeping sheet with me? It will take virtually no space in my suitcase! Also, do hostels provide blankets?
Please let me know,
