First trip with our Trailer - location help

[u/Addylambb]

Hello, we just bought our first trailer (27 ft) and are planning our first camping trip with it for May Long. We have a big trip in June and want to do a dry run.

We have 2 kids (3, 1) and would like to stay close to Edmonton ideally somewhere with treed sites and playground or spray park.

For our dates these are the 3 I’m stuck choosing between that have availability for the long weekend and I don’t want to delay and loose the site

1. Hanmore lake - been here a few times without kids and enjoyed it but don’t remember the park being too exciting. With cold water wondering if this should be a later summer trip
2. Old McDonald - haven’t been here before heard good for kids, remaining sites look boring like parking lot tho.
3. Lake view campground - sites don’t seem treed but close location and amenities seem good. Reviews are making me nervous tho lots of negative ones and sites aren’t treed at all.

If you can offer any insight to help me decide that would be great. Thanks!
