Another solution. Get a White label Travel Affiliate Program. A few Affiliate programs offer it: Expedia, Priceline, IHSAdvantage, Bookit.net, etc".
That way you don't have to worry about cookie tracking and you can build you own brand.
But we warn: you conversion will suffer short term. You white label will not have the brand as a big name, so people might not book.
But to be honest, cookie stuffing is extreme in travel. And so programs have 30-45 day cookies. You click a ad on Facebook about a destination and you're cookie for the next 45 days and affiliates afterwards get no credit depending on the program term.
In travel affiliate it's "First Cookie" Advantage. The first to get the customer when they start search for hotel and place as many cookies for all the major travel sites as possible and wait for them to finally convert.
