Not really. A startup's need is always revolving around what the founders can pull off- how creative and how shameless you are.
Lets think outside the box here:
If you absolutely have to market during a break, follow your potential users. Showcase at events, attent clubs, the beach, go to the destinations even in Mexico where a lot go to and ghand out download cards with codes.

Go to hiking places and leave then in their cars so they find them on their way home.
Go the places where the app would bring more value to them if they downloaded in that moment.
