Getting married in Ladakh is not as easy as it seems. Altough the connectivity is nice as LEH has an airport. 

Hotels are just 4-5 hours  from the airport.

You will need 3-4 days to assimilate before you can enjoy your wedding in Ladakh.

Points to take care :

Do health checkups before coming to Ladakh

Visit the property before you plan the wedding in Ladakh

Keep fit to enjoy the weather. Dont expect a large entourage with the wedding. Try to keep it a small and subtle affair.
