Make sure you check the freezing levels and also their trends as well as is happening with weather systems, etc. Then you want to leave yourself a good bit of room between your cruise altitude and the freezing level. Talk to your CFI and work out with them what a good bit of room looks like for you.
Remember to take terrain and any legal altitude restrictions/requirements.
What has been drilled into me several times is "don't flirt with the freezing level".
Since you've been waiting two months to go, you're obviously sick and tired of putting it off, but I'm the person who had to wait 4 months (count them!) before being able to go on my checkride due to weather and examiner availability
