There is no substantial difference. Native speakers would say either one.
What's the difference between saying:
Maybe we could make a trip to Florida next week.
Maybe we can make a trip to Florida next week.
Are both the same? What would a native say?
So, why do some say can and others say could?
There's got to be even the smallest difference.

And you have been told before that non-standard words like 'gotta' are not acceptable on this forum.
