InDesign is DEFINITELY NOT a web tool. You should use Muse which is an excellent web tool by all reports I've heard.
And if you know InDesign, implementing Muse is a breeze.
Thanks for the comments.
I am new to InDesign but already like the environment and the concept of web design from a publishing perspective.
My unsderstading is Muse is subcription-only and not stand alone software I can buy as a one-off purchase.
I only want to make one or two websites updating them from time to to so a monthly subscription seems a bit much for my needs.
Of course, Muse sounds pretty cool though. Easy for a dummy like me to use.
My current web site is pretty appalling. It's an interacitve PDF here:
EDIT: If the purpose is to showcase self-catered accommodation, I should consider using existing online providers like "stayz" or whatever. Will go check out these options when possible.
