I check three things when looking for a hotel: Price, Guest Reviews and Bedbug Reports. I've stayed in one hotel where my wife and I left with over 150 bed bug bites between is us.You'd be surprised how many resources are out there that measure bed bugs in hotels.
I use tripadvisor, agoda and wotif to gauze information on potential accomodation arrangements. Price, amenities, proximity to tourist attractions, customer reviews have quite an influence on my decision-making process when comes to choosing a hotel.
Since 2003, our holidays have always been on a cruise ship. Ah yes, we stayed in 2 hotels during a 3 week holiday in Bangalore India, for a family wedding. Then 3 days in a cheap hotel in Singapore, before the Bali wedding (2017), where we stayed in 2 home stays in Bali, during a 2 week stay for a 2nd family wedding, but they were the only non cruise holidays we'd since since 2003.
When visiting our granddaughters in Melbourne, we stay with the youngest daughter (without the kids), so we don't need a hotel in Melbourne.
