Meaning
A hotel building decorated with a big heart, often in pink. It refers to the Japanese love hotel, a short-stay hotel for couples rented by the hour or the night.
Because of that origin it carries a suggestive meaning, so use it with care in family or work chats. Couples sometimes use it playfully for romantic getaways: “Booked somewhere special for our anniversary 🏩”. For an ordinary stay, 🏨 is the safe pick.
