We are a family of four adults ranging in age from 19-58yrs from the UK. We have 7 nights to split between Banff, L. Louise, and Jasper, before taking the train from Jasper to Vancouver for another week. At first we thought we would do Banff for 3 nites, LL for 2 nites, Jasper for two nites. Now thinking we should not actually stay overnight in L.Louise at all, but add one extra night to both Banff and Jasper instead. We would then visit LL for a few hours on the drive from Banff to Jasper. Is this wise? OR do we need 1-2 nights to 'do' Lake Louise properly? Any thoughts on this would be very much appreciated.
