Wildlife photography holidays with limited mobiltiy

Hi

I'm after some advice please? I've recently been diagnosed with a neurological condition that gives headaches, pain and is limiting my mobility but not needing a wheelchair so far. I will likely need neurosurgery.

I've been traveling for wildlife photography the last 10yrs and unfortunately my usual types of trips are now too strenuous.

I'm looking for ideas for wildlife holidays that are more accessible: eg places with limited hiking or wildlife viewing from a car etc. I like the look of the Canopy Tower in Panoma or somewhere similar with birding/wildlife viewing from the accommodation/in the grounds of the accomodation.

I'm also thinking maybe a cruise or river cruise with easy port stops or ones that can view wildlife from the ship?

I've done Costa Rica, Kenya, Namibia, India, Galapagos cruise, Ecuador, Romania and Gibraltar as a flavour of what I like to experience. I'm a solo traveler and would either organise these trips myself or join parts of it with other photographers.

Any ideas would be appreciated 👍
