Photos do not show the final bill
A hotel page can sell the room before you have checked parking, breakfast, pet terms, spa access, cancellation, deposit and local transport. Those are often the pieces that decide whether a break fits.
Check the non-room extras
Parking, breakfast, charging, pool or spa access, late checkout and pet fees can change the real cost. Write them down before comparing hotels.
Check cancellation timing
Look for the final free-cancellation date, deposit wording, amendment rules and what happens if you arrive late. Screenshot the terms at the time you book.
Check room fit
Beds, sofa beds, cots, lifts, accessibility, air conditioning, noise and walking distance can matter more than the hero image. Check the boring details before you commit.
Use UK Shortlists next
Use the summer hotel break checklist before opening hotel pages. It helps you compare the practical terms, not just the room photography.
