Hi Shastie
We went last April and are looking to go this April too, we went last year on the 18th and things were opening the week we were there so maybe the 5th is slightly early, the weather was lovely and only slightly chilly on an evening. Bear in mind April
Icmeler is very different to July/August Icmeler and not everything will be open. When we were there the majestic was just opening on the Canal, but the Venice wasnt open so dont do what we done and decide where you are going before you get there! You may be disappointed!!
