Hi all, am planning a trip to Chiang Mai for December. Looking to rent a dtracker or something similar. Is it possible to get fully comprehensive rental shop insurance? Any idea if I need to sort this on my holiday insurance before I go? Lastly, I've got a big head ;-) I wear an XXL helmet in the UK. Will I be able to buy a decent one this big in Chiang Mai or do I need to bring my own? Cheers, any advice appreciated.
