so we have given this long enough and Edinburgh has the most votes and Brussels second . my concern with Edinburgh is cost of hotels , they are coming out 2 - 3 times more expensive than Brussels.
The travelling costs for most people would be the same for both destinations. Brussels would work out cheapest option. but overall costs would be higher for Edinburgh .
i have set dates for June in this comparison

i have phoned round a couple of hotels and there is not much availability in Edinburgh at the lower priced hotels in June ( and i don't mean cheap 1 or 2 star ) .
if we can come up with a date and hotel choices for both locations we decide from there .
