Hello All Thanks for much for your inputs. At leats 1 thing I have decided is that we will fly from Sea-Calgary rather than drive to jasper/banff as we would like to use the 5 days to actually see the gorgreous places you all have mentioned!! And yes I am very aware that 1 trip or just 5 days dont do justice to these parks and I have all intentions to go back again. I am still undecided about May memorial ( 23-27 May) or July independence day ( July 3-7). the calgary stampede also happens in July so I am guessing those make the parks also crowd up a lot and places to stay are expensive. So is the crowd a major deterring and delaying factor to get to places or is it ok...how different will be the experience in May end ...just marginally different or dramatically different....does May last week mean its still going to be too cold to wlak comfortable around with a 11 month baby or is it not that bad... I would love to hear more ...thanks in advance for taking the time to reply
