Going to Montreal with two 5 3/4 year olds in April - suggestions?

[hollybloom24]

We'll be staying in Old Montreal at the Nelligan Hotel for three days and two nights. We are going mid-April, so weather might be chilly, but not opposed to being outside.

Any thoughts what would be good ideas for activities for two almost 6 year olds? Biodome for sure. Anything that isn't worth seeing?

Any cost savings tips, like buying museum passes ahead of time, or is there a city pass that allows you to visit multiple sights? How about traveling around to different parts of the city without a car?

Any good adult restaurants that are kid friendly that people have visited for lunch or dinner?

TIA!
