空参数显示错误404 .htaccess

Question

https://northbengaltourism.com/hotel-details/sikkim/lachung/NBTH0329/正常使用：

<button type="submit" form="firstForm" value="Submit">Submit</button>

在htaccess中。但是当缺少两个中间参数时，页面显示：

RewriteRule ^hotel-details/?(.*)/(.*)/([^/]*)/$ hotel-details.php?hotdest=$1&hotcity=$2&hotelid=$3

我尝试Error 404 (Not Found). https://northbengaltourism.com/hotel-details///NBTH0329/取代([^/]*)，但没有运气。请帮我解决这个问题。
