What can i do to spice our vacation up?

Me and my fiance have been having trouble in our relationship. We just had a baby and have been arguing a lot. We are going on vacation alone to try and find "us" again. What can I do physically sexually and emotionally to help it along? We are staying in a resort for three nights. I'm very excited cause we haven't had alone time in almost a year. I need sensual sexual ideas as well as sensitive emotional ones. Help please!!!
