5min walking distance is not possible.., the current phase is the back part , hence you will have to walk thru the front blocks even to get to the main road (next to first world). That would already take more than 5 min.
Even on the main road, there is no access currently to First World Hotel.
Been to the sales office last weekend, the bridge is verbal and a sales pitch, if it's an agreement they already gotten from Genting, it would be clearly communicated as a sales pitch for sure..
Well, end of the day they will for sure offer free shuttle bus /van service from the hotel lobby, hence I don't see the bridge /walkable distance is a key issue here. Taking into account as well, if they
hotel are majority occupied by tour groups/holiday goers, walkable or not is not a consideration (or even a known aspect) when they choose which hotel to stay at.
