As Glaciers said, many of us would rather leave half of our clothes at home than any "necessary" camera gear, but the choice is entirely up to you based on your personal cruise/photography balance. Personally, I cruise to get to new places to take pictures. I truly enjoy photography and have looked at the world as a possible composition since I picked up my first camera at about 10 years old. Not taking my primary camera(s) would be unthinkable. If you are a casual photographer and don't spend a lot of time with your camera, the phone and the Oly should serve to capture the occasional sunset, wide view of the Hawaiian scenery, fellow travelers or fancy dinner shot. If you like to shoot a lot, the phone isn't going to cut it. I have a Pixel XL and even its spectacular camera falls short in very low light (I mean very low) and in any situation where a telephoto is needed. All of our advice is well meant but the decision is ultimately yours and will be based on your perceived need for the advantages an interchangeable lens camera gives you.
BTW, our last trip to Hawaii was a bit more adventurous with a boat tour out to the lava flow. If I were cruising to Hawaii and had a stop at the Big Island, I would take the tour again without hesitation.
This is, pretty much, how Ieel. Of course, as has been stated, the choice is yours. I, simply, cannot imagine taking a trip like that without bringing, at least, one of my DSLRs (I have 2). I would bring the lightest one if that was even an issue. Now...me....I rarely travel without both of mine after a hard learned lesson when I brought one of my bodies with me on a trip through The St Lawrence Seaway and my camera died mid trip and I had nothing to shoot with for the rrst of the trip. I vowed that would never happen again.
For me, using a phone as my primary camera just does not make me feel very comfortable, as good as some of today's phone cameras may be.
