I am member of the Internations milano community and me and my friend are planning a holiday in Oman. we arrive on friday in muscat and on saterday we would visit the centre, than on sunday we would like to make a daytrip. For example to the grand canyon of oman. Does anyone has tips on how to organise this? we are on a budget and we have no car, so if you now someone who could help us, please let me now!
