There did not have any available at Thorntree but I didn't even use the set I brought. This is a river lodge so you can easily see much of the wildlife without them.

We found Thorntree River Lodge to be very accommodating. So, I recommend that you negotiate the excursion to the Zimbabwean side as part of your package or a very small fee. Regardless of high/low water levels, a day's excursion easily accommodates both sides of the falls. And the guides at Thorntree do an excellent job of both. Note that you do go thru immigration on both sides. An important point tho -- on entry to Zambia, make sure that the entry visa you get includes the cross border trip to Zimbabwe as you go and return the same day. Re the water level -- we are not experts but I suspect that June is kind of "mid season" so that the water levels should be mid level depending on the rain fall and of course the drought conditions they had been receiving. We found the people at the Zambian Consulate to be very helpful also. BTW -- the Falls are spectacular - even at low water when we saw them with very little water coming over on the Zambian side. The Zimbabwean side is by far the best and easily self guided as the Zambian guides are not allowed to guide on the Zimbabwean side. The guides escort you thru the border and drop you off at the entrance to the "park". We did it with a 2nd couple from the lodge -- takes about 90 - 120 minutes. Hope this helps.

Yes -- as long as you have a plug adaptor, there are 220 volt outlets for phones, devices, curling irons, etc. Note -- there are no wifi facilities in the rooms. But wifi is available in the library which is nicely equipped but not as convenient as your room

Yes you can and we did. Re adaptors -- email the lodge and ask or do a google search on the standard receptacles/plugs for Zambia. As I recollect you can use the 3 prong UK square adaptors or the three prong round ones
