Regards

I've a B&B and often my guests are english or talk in english. I'd find a nice way to welcome them and when they leave my structure.
Many times i say them something like that "Welcome, my name is Alessandro a this is my sweet guesthouse. Can i offer you something to drink, how has your trip been so far, did you have any problems?".
Are this kind of sentences correct?
Wheares, when thay leave from my B&B i've a little more embarrassment. Can you suggest me something.

Thanks
