I recall having the same consternation the first time I used it earlier this year. But I got the hang of it pretty quickly and then found it easy to use. You shouldn't encounter any problems
I found it pretty easy to use but went during Thanksgiving week and had all sorts of technical issues. A lot of times asked for me to sign in or send a password to e-mail over and over again and my DH and I could not both go on and make selections would get error messages or would just sit there. Also, one thing to keep an eye out for is when you make a selection as you are going through the different screens can sometimes change a time on you.
