Dear Mrs. Sophia Lauren,
Hi, I received your e-mail of today March 7, requesting a change in reservation plans.
Because your flight was overbooked, you want to change your current reservations from Wednesday, March 20 - Friday, March 22 to Friday, March 22 -Sunday, March 24.
Although I definitely changed your reservation as you wished, your confirmation number has not changed.
If you need to make any further changes, you don't need to send me e-mail any more. You can just visit our website at www.hotelshell.com and change whatever you want by clicking the "Reservation" link. You can access reservation information by entering your confirmation number. No additional fees will be added if your changes are made 36 hours before the check-in date.
It will be very easy to check if your changes are correct, because confirmation will be e-mailed automatically to you immediately.
Thanks for choosing Hotel Shell. We are looking forward to serving you soon.
Jim Morris
Receptionist
