If you have a large enough group, private tours with G Adventures is great. That was my Iceland trip. My Peru trip was just a normal tour. We didn’t have enough people. For New Zealand we used a different company.I'm quite comfortable with luxe, and have stayed at the Peninsula Hong Kong. For us, I just don't NEED it on every trip, especially not when paying for 6 of us. Our G Adventures trip is almost exactly half the cost of the ABD for the same amount of days, a few less meals, and 4 star hotels. And it's private, just the 8 of us, with our own guide, which I think outweighs the "leveling up" of the hotels.
I'm actually more wanting to say that as a female that's traveled solo, I don't think you need Peninsula prices to be safe, but I completely understanding liking the luxe. We stayed at a hotel in Andorra that was so nice, it had amenities I didn't even know existed. Holy cow. I never wanted to leave.
