It's interesting to see all the comments regarding the comparisons between Travelodge and Premier Inn, and how the majority of contributors to this thread rate Premier Inn over Travelodge. I have only ever stayed in Travelodge's so far (my first stay was at London City Airport in 2015, and have since used several of their hotels in London, Lowestoft, Blackpool and Glasgow), and by and large my experiences have been generally pleasant. I've never expected too much from them, knowing they are a budget hotel chain, so I guess my standards aren't too high. I particularly like staying at the Lowestoft branch, as although it's pretty much no-frills (no on-site restaurant and no super rooms), the standard of cleanliness and general ambience have always been pretty top-notch each time I've stayed there, plus you have a Harvester next door to it and Tesco just the other side of the road too. Being 4.5 rated on Trip Advisor also goes to show this branch is pretty highly-rated.
The reason I've stuck with Travelodge over Premier Inn is the equivalent Premier Inn hotels at where I plan to stay have generally been around 20-30% more expensive, so I've opted to take the saving with going with Travelodge rather than Premier Inn. However, looking up the prices that I did last night for the post I made, it does seem the price difference has somewhat disappeared now. If the MCM Comic Con goes ahead at the ExCeL this October, where I would normally book the Woolwich Travelodge for a weekend stay for that, I may consider giving Premier Inn a try instead.
