Honeymoon travel agencies/advisors you’d recommend?

Hi guys!

Planning our honeymoon for Feb-April 2035 (exact month tbc as we have decided not to go directly after our wedding in November).

We are currently thinking of doing a two destination honeymoon in central/south America – Brazil, Costa Rica, Mexico are our top options.

Does anyone have any recommendations of (ideally UK based) travel agencies or package providers? I don’t want to be mugged off and there seem to be so many different providers it’s hard to tell who might be decent! I want to stay away from flight+hotel packages directly via an airline, rather we want a service that will help us arranging activities, upgrades, etc as well.

We like the look of Kuoni – has anyone tried them?
