You unpack once and wake up in a new city — from the vineyards of the Rhine to the Danube's storybook capitals. Right now the Globus family is running one of its strongest 2027 offers, and the river-cruise piece has the tightest deadline: on select Avalon Waterways Europe sailings you can choose free international airfare or up to $1,500 per person off — but only through August 10. The same promotion trims $500 per couple off select Globus land tours and $300 per couple off Cosmos trips through August 31. If a 2027 river cruise is on your list, this is the week to lock the date.

The free-air option usually wins once you price transatlantic flights for two — on most summer 2027 dates it quietly beats the $1,500 credit. If you've been waiting to try a river cruise, this is the offer I'd move on: the panoramic-window suites on the newer Avalon ships sell out first, and I can hold one while we sort the details.
