Enumerating with Prepositions: ''To''

Question

I have a question about the use of prepositions when enumerating things or talking about multiple actions. For the sake of simplicity, I'm only going to use "to". For example, in the phrase:

"You have until X date to register and be eligible for the draw. Grab this chance to participate and have a chance of winning a car"

Is the sentence correct as it is? Or would it be necessary to repeat the "to" after listing the consequence of the first action? As in:

"You have until X date to register and to be eligible for the draw. Grab this chance to participate and to have a chance of winning a car."

Thanks

When two or more infinitives/infinitive clauses are connected by

and, or, except, but, than, as well as

the infinitive marker to is almost always omitted after the first one:

My mother asked me to feed the fish and to walk the dog before she came home.

The cookies are fresh from the oven. Would you like to have one now or to wait until later?

I could find nothing to do this afternoon, except to read my book.

After three solid days of rain he couldn't come up with anything to keep himself occupied but to stare out the window.

In this traffic it's quicker to walk than to take a cab.

Before the party I have to buy more wine and cheese as well as to pick up the dry cleaning.
