Hello. I just realised that I can go on a 4 day long weekend -- April 28 to May 1 as May 1 is a public holiday in Singapore. I've been in this part of the world for a long time now so I think I've gone thru most of the "easy weekend" trips. Seeking suggestions/recommendations that :,
1. Good for solo travel.
2. Accomodations / BUdget : More a little bit higher on the backpacker budget ; but definitely not luxury. I don't want to spend for a hotel room where I'll be out exploring most of the time anyway. I'm Ok with AirBNBs and staying in a room instead of renting the whole place.
3. Interests : Very open. I can go scuba diving, hiking, exploring local sights, shopping, getting good quality and value massages, just chilling.
4. Timing - Hopefully there are enough flights from Singapore that I masimize the 4 days. Hoping to fly out on April 28m Saturday morning, fly back on May 1 evening, even if I arrive at midnight. As long as in time for work the next day!

Thanks

Given your range of interests, I'd suggest Sentosa island - you can scuba dive or just relax with a great spa session here.

4 days is a long travel in SG try going to Indonesia or other neighbor country.

If you want something adventuresome, a flight to Malaysian Borneo, either Sabah or Sarawak would be a fine option. There are non-stop flights from Singapore to both Kota Kinabalu and Kuching.

Or consider a trip to Central Java to visit Borobudur and Prabanam.

Also consider Georgetown, Penang in Malaysia known for it's fable hawker food. It's also a World Heritage city,

While you could go to Bali, 4 days really isn't enough.

Sentosa is basically a theme park, nothing adventuresome there.
