I know there are some "easter eggs" that shows all ladies in the game naked, but, if you don't find such easter eggs, the nudity level is low or moderate? (like previous games)

I think there might be at the nudist pool area. Maybe in the ballroom where you're under the pool.

There is a nude scene/pic for all the main girls in the game. And yes, all of them are easter eggs :)

In Drew's case there three possibilities even. Move leaf, don't listen and stand while she's walking. Now you only need to figure out how :)

Nudity and sexy scenes you will always encounter while playing (i.e., without easter eggs):

• Nude, but strategically covered women and men walking past the changing booth at the pool, half of them made sexy, half of them uglified caricatures
• Nude women and men at the pool area with some sexy bits visible, but very far away and tiny, and mostly caricatures
• Nude women and men with some sexy bits visible seen from under the pool, but again mostly caricatures
• Non-visible fellatio performed on Larry (she ducks below screen, but it's obvious what's happening)
• Nude, but strategically covered Larry being caught by various people while running to his room, purely comedy relief
• One of the main girls is fully nude and seen upclose, but she's also strategically covered
• Another main girl gets down to her bra only (bottomless), but even though the table is made of glass, you see nothing thanks to her drink

What I mean by "caricatures" is that the background nudity in Larry 7 is less titillating than what you get to see in Larry 6, where you face no unattractive girls, and even the nude men in the shower area are meant as eyecandy for girls (as said by the Narrator). Here, the background nudity contains some women you likely don't want to see, and all the men are mostly intentionally ugly, even a little disturbing at points—there's a Ron Jeremy type dude with extremely hairy chest who walks past the changing booth naked while looking straight at you (the player) with a sleazy grin. Almost as if the joke was that they sabotage your plans to use the game as "inspirational material". This doesn't apply to (almost) any of the encounters with the main girls.

If you complete the game with maximum score and only after having found all the Waldo-Dildos, you get a surprisingly explicit, albeit short softporn scene with Captain Thygh during the epilogue animation. I don't remember if this requires you to get all the easter eggs or not though. But it is something you might unexpectedly see when you try to get all the points, which many players will probably do naturally.

The rest is hidden behind easter eggs. Two or three are perfectly discoverable by accident. One of those includes full view of breasts, and it is heavily hinted at. Another involves full frontal nudity with two girls, that one requires performing an action on an object which you will need to perform in order to complete the game, it's just not the right "version" of that object. The remaining scenes mostly show breasts, but they are nearly impossible to get unintentionally.

It depends on your standards, whether you consider the sexual encounters without easter eggs as too much, or too little. Unlike the background nudity, they are (almost) all clearly intended as sexy situations. It also depends on whether you can even see Larry 7's "Disney-like" cartoon style erotic at all.

Ok, I think that's it. I have played the game just two weeks ago, so hopefully I haven't missed anything. Overall, I'd rate it a little bit less sexy than Larry 6, except for the final reward scene, which the closest Larry ever got to a real softporn adventure. That would make it the second sexiest game out of all games with Larry. At least until someone makes a remake of Larry 4 with less pixelated graphics.
