Welcome to Safaritalk!
It's very nice of you to join us.
Your avatar image immediately seized my attention!
If it's ever comfortable and convenient we'd enjoy reading a self-introduction in the Introductions section.
Tanzania is so well described by trip reports in the Tanzania section that it requires no further fanfare.
Top quality sightings, excellent biodiversity, and well-run lodges and camps. Your future husband and you are sure to have a lovely honeymoon in Tanzania.
I've visited Kenya for ten safaris, including one earlier this month.
It may be different than Tanzania, but it's unclear how any one location might objectively be better than another.
What stood out to me in your nice post was your interest in seeing “incredible landscapes”.
Might I please mention the names of both Meru National Park and Samburu National Reserve?
At present, respected Safaritalk members @TonyQ and @offshorebirder have posted trip reports showing their recent first-rate safari experiences in those locations.
Both Meru and Samburu feature the wildlife species you've mentioned, plus their settings are spectacular, especially in afternoon light.
I hope that you and your fiancé will have a wonderful honeymoon in East Africa!
With Best Wishes,
