Is the tamron 18 200mm f 3 5 6 3 di iii vc good for travel?

Yes, it's a sensible travel zoom. On APS-C it frames like about 27-300mm on full frame, so one lens covers wide landscapes through to tighter details without changing lenses on a busy square. The optical stabilisation helps with dim churches and markets. It's discontinued, though, so check used stock.

It works best on an APS-C body, where you get its full framing:

• Sony a6400 for a small, everyday travel kit.
• Sony a6100 if you want to keep the budget and bag size down.

If you already own a full-frame Sony such as the Sony a7 III, it still fits, but it runs in APS-C crop mode, so you get fewer megapixels.

For the full checklist of what to weigh, see Travel.
