I just read a thread of a brother being sceptical about attending a church in the hotel. Here are the reasons I think might inspire this

1. Jesus would have done the same i.e. spreading the good news around

2. ease of worship. not everyone in the hotel are there for immoralities. Some for businesses, events and ceremonies.

3. Majority of churches in Asia and middle east are in the hotels and whatever space they can Garner. Because of restrictions from the countries to build churches, they end up paying heavily for hall in the hotel.

Wherever you see a church today, be grateful and worship God in spirit and in truth

Forget your logic of ease of worship and spreading the gospel around.

Churches worship in hotels because of unavailability of a good space elsewhere. How many lodgers who are not members of the denomination join the service? In fact, how many lodgers who identify with the denomination join the service in the same hotel while lodging?
