Oh of course!

I do wear silver, so I do not buy.

Playa los arcos has an all inclusive option but I don’t think it’s 4 stars, but the location is excellent. I know there are a couple all inclusive that are a little closer to downtown, and that’s only a few blocks away from the malecón. Sheraton buganvillas is a 4 star hotel I believe, they have an all inclusive option and it’s a 5 min cab ride to the malecón

No time is long enough. I can walk the Malecon for hours. You always see something new. The Statues are amazing, the people are kind and helpful, the street vendors are fun and the food is amazing. I lived along the Malecon and never got tired of it. I spend half of my months in Puerto Vallarta walking the Malecon.

Yes it is the southern part. Yes you can take the Centro bus, but you will be 3 blocks from Malecón. At the end of the route, your bus will turn right (towards water) or left, towards the Main Street. When the bus slows down to turn, be sure to ask driver which way he is turning. If R, stay in until he stops in about 2 balks. Then get off, cross the street and go 1 block. If he turns L, no panic, as he will stop in 1 block to p/u more pax. Just get off there and walk back the way you came from. Don’t worry, hard to get lost. A good landmark is Daquri Dicks. That corner is where Uber drivers p/u. But you must have the PV Uber app on your phone. Taxis are pricey. Walk up the street where u got off your bus. Walk to the main st. There are 2 corners where many will be waiting for a bus. Ask someone if Walmart bus stops here. Take a bus that has a Walmart sign. It’s across from port. Enjoy.

I would recommend starting at the Plaza area and go north from there. As I understand, UBER works well in the area, but for comparison we used a taxi from the cruise dock to the plaza and it was only $3 US per person for 4 of us. Have fun!

i didn't try any local food. I did use uber to get around the city from the hotel to malecon. Totally safe.

hola en febrero es buena época para estar en vallarta, pues no hace calor y el mar es frío la ventaja de esa época es que puedes tener avistamiento de ballenas muy cerca de la playa, es todo un espectaculo.

Both of the above answers are thorough and good.
