I agree that you could use a period instead of an exclamation mark at the end of the last sentece. I would also omit 'will', since it sound more natural without it. Usually when we are giving well-wishes we do so in the present tense, so we would say "I hope you have a great day" or "I hope you enjoy the party" or "I hope you have a good weekend".
