It is possible for a hotel to be fully booked on site even if it was booked online. This could happen if the hotel's online booking system has not been updated in real time to reflect the current availability of rooms. It is always a good idea to confirm your reservation with the hotel directly, especially if you are concerned about the possibility of the hotel being fully booked on site. **

Yes, I have booked a flight with Opodo but did not book any luggage. I prefer to travel light and only bring a carry-on bag with me. This helps me save time at the airport and avoid any extra fees for checked luggage. Additionally, packing light allows me to be more flexible during my travels. **

Heating oil can be booked through various methods, including online ordering, phone orders, or through a local heating oil supplier. Customers can typically choose the quantity of oil they want to purchase and schedule a delivery date that is convenient for them. Some suppliers also offer automatic delivery services, where they monitor the customer's oil levels and schedule deliveries as needed. Payment for the oil can be made at the time of booking or upon delivery, depending on the supplier's policies. **

The booking will be confirmed as soon as the payment is processed and the reservation is confirmed by the booking system. This typically happens instantly if the booking is made online. If the booking is made over the phone or through an agent, the confirmation may take a little longer as it depends on the availability and processing time of the booking system. It's always best to check the specific booking terms and conditions for the most accurate information. **
