Which would be correct? Or are they equivalent?
- I present this award to Sam and to Tom.
- I present this award to Sam and Tom.
If it's a single award to two people and they have to share it (e.g., it's a solid gold loving cup and there's only one in the world), then I'd say "to Sam and Tom". If each gets a separate iteration of the same award (e.g., it's a solid brass loving cup and there are two, one with Sam's name inscribed on it and one with Tom's name inscribed on it), then I'd use "to Sam and to Tom".
However, because it's the same award, it shouldn't matter which one you choose.
