I am not sure of the G7, but I do have a FZ300 which I love because of the versatility, the great zoom reach and of course the image quality. Me, I would have NO problem with just the FZ300 just for convenience sake.

I don’t know all these models but take your best camera and lenses. Alaska deserves no less. You will have your cell phone anyway if you go out to dinner or something. For me a huge part of the fun of going on vacations is taking pictures. Take the camera you like using the most.

Been there, done that. If you're into photography at all, you'll regret it if you don't take the G7 and lenses. Here are examples taken with an Olympus SH-1 and an Olympus EM-1 (similar to your cameras).

My advice: The G7 and both lenses. At your excursion stops put on the lens for what you will be seeing that day. Use your phone for backup for situations where the lens you took that day doesn't cover everything. Switching lenses on excursion trips is a real pain in the ass ... what I actually do myself is take two identical cameras and leave the lenses on them. That's where the small size and weight of m4/3 is so great (I use two GM5 bodies).

I too, found it MUCH better to carry TWO cameras! One with wide angle zoom, and the other telephoto zoom. While in Alaska/Yukon, (1st time), I found I missed shots because the wrong lens was on the camera, so I started bringing two cameras. So the use of a cell would fill the bill now, ... maybe. The shot in particular I missed was a really cute baby black bear in a tree, another was of 3 bald eagles on an iceberg (two flew off), but there were others.

My wife and I cruise regularly but Alaska holds no fascination for either of us so we've never been.
I always take my DSLR (currently a Canon Rebel EOS T7) and my Panasonic DMC-TS1 which fits in my pocket nicely.

My T7 with a couple of lenses is my go-to for pretty much everything, the Panasonic comes out when there's a chance of things getting messy (rain, snow, sand, haboob, etc).

Take what you want since you're taking your hotel along for the ride and enjoy the trip! I post all my shots on Flickr, have a look if you're interested:

I suggest that you look closely at the shore excursions you plan to take and also the amount of time you will be spending in Victoria, BC. Except for the day you visit Glacier Bay, most of your time at sea will be spent in open ocean or motoring at night. So your big opportunities for photography are Glacier Bay (where you can get beautiful shots with any length lens), on shore excursions (completely dependent on which ones you choose), Victoria (the same as any other beautiful, fascinating city), and on board.

As an example, my wife and I cruised Alaska in 2004. My interest in photography was just getting rekindled. I took a Olympus OM-2n and a 50mm f/1.2 lens and didn't miss anything of serious value. If we'd gone to the lumberjack show (we should have), a somewhat longer lens would have been beneficial (maybe 100mm or so).

Keep in mind that the Inside Passage is a coastal rainforest. Clouds and rain are the norm. We had lots of sun on our cruise, but that is not the most likely weather. Gray and rainy is. Prepare for rain and wet when ashore. If you go on a whale watching cruise, prepare for salt spray and wet (and mayhe rain) on the small boats. There are protected dry seats, but they are usually behind flexible transparent curtains which are not photography friendly.

If I went on a cruise tomorrow, I'd take either my D500 (DX) or D850 (full frame) and a 24-120mm f/4 lens. Either one would do great.

I forgot a camera when I wen t to my twin grandsons' graduation last month. All I had was my iPhone. I got just as usable images with it as I would have gotten with all the big gear.

If it were me, there is no doubt in my mind it would be the G7 and lenses. And even though what you have is great, you might want to rent/buy the G9 or GH6 and make the G7 your backup camera. Of course, this is very dependent on your shooting. If you shoot a lot on trips, the G7 is the way to go. If you only plan on shooting a 100 or 200 total shots (~15 to 30 shots per day), then you might want to consider the Lumix FZ300.

Have only been on ONE Alaska cruise. Took everything with me. No "point-and-shoot", but my longest lens was a 70-300. For most of what I shot, it was enough. However, for eagles and whales… another 200mm would have been nice. Even 300 wasn't enough because the eagles and whales were too far away. For most of everything else, what I had was sufficient. Unless you're after "wildlife", any pocket "point-and-shoot" or even phone camera would be enough.

There are two types of vacations when your a photographer
A- time to unwind and relax , family vacation = small pocket camera
B- time for some serious photography = take it all

I am going on a cruise on the Rhine River next month. I just purchased a Panasonic Lumix ZS200 - 20.1 megapixels, 1 inch sensor, 24-360 mm zoom to take with me. I can put it in a small pouch that attaches to my belt. I have a Fuji mirrorless camera with several lens, which I use for specific photo shoots, but I don't want to drag a bunch of equipment sightseeing. I have owned numerous Panasonic point and shoot cameras, which produce good pictures when traveling.
