The Internet is a wonderful resource for planning a trip, but sometimes what looks good on the computer monitor turns out to be not so great in real life. It's important to be careful when making your vacation arrangements online: you want to be sure your vacation is one to remember - because you had a good time, not because of your awful hotel. About's Guide to Honeymoons and Romantic Vacations offers advice on how to judge a hotel by its Web site. Choosing the right hotel for you can make the difference between a vacation that's memorable for its delights and one you'd rather forget.
