1. I’d make the template wider.
Your #wrap_talia is only 930px wide. Try setting width of all your containers in %. It will work great.
2. Navigation menu is white-on-yellow.
It’s hard to read.
3. Searchbar will look more compact at top right, not center.
4. Look at the footer.
The copyright thing (? 2009 Alcudia Holidays) should go the second, not the first.
5. And maybe add some more information to the main page.
Though there are a lot of useful links, it looks a little bit empty.
6. Links are great. Because they are underlined and change color )
But for example here:
https://alcudiaholidays.org.uk/package-holidays-alcudia
yellow-on-green = not good.
7. Let’s make a trick.
Switch off all images and look at your website. See it?
Never let bad background to steel your information.
What i almost adore is the way your sidebars are positioned.
I mean the code.
That’s great, though i rarely see such an organization )
